Problem:    When a 0xa0 character is in a sourced file the error message for
            unrecognized command does not show the problem.
Solution:   Display 0xa0 as <a0>.

Problem:    Redobuff doesn't always include changes of the completion leader.
Solution:   Insert backspaces as needed. (idea by Taro Muraoka)

Problem:    "C" on the last line deletes that line if it's blank.
Solution:   Only delete the last line for a delete operation. (James Vega)

Problem:    Calling debug.debug() in Lua may cause Vim to hang.
Solution:   Add a better debug method. (Rob Hoelz, Luis Carvalho)

Problem:    Crash when 'colorcolumn' is set and closing buffer.
Solution:   Check for w_buffer to be NULL. (Yasuhiro Matsumoto)

Problem:    Opening a window before forking causes problems for GTK.
Solution:   Fork first, create the window in the child and report back to the
            parent process whether it worked.  If successful the parent exits,
            if unsuccessful the child exits and the parent continues in the
            terminal. (Tim Starling)

Problem:    Missing parenthesis.
Solution:   Add it. (Benjamin R. Haskell)

Problem:    One more warning when compiling with dynamic Python 3.
Solution:   Change PySliceObject to PyObject.

Problem:    Can't compile with tiny features.
Solution:   Add #ifdef around win_valid().

Problem:    Complete function isn't called when the leader changed.
Solution:   Allow the complete function to return a dictionary with a flag
            that indicates ins_compl_restart() is to be called when the leader
            changes. (Taro Muraoka)

Problem:    Code not following Vim style.
Solution:   Fix the style. (Elias Diem)

Problem:    Warnings for pointer types.
Solution:   Change PySliceObject to PyObject.

Problem:    Writing to 'verbosefile' has problems, e.g. for :highlight.
Solution:   Do not use a separate verbose_write() function but write with the
            same code that does redirecting. (Yasuhiro Matsumoto)

Problem:    Python 3 doesn't support slice assignment.
Solution:   Implement slices. (Brett Overesch, Roland Puntaier)

Problem:    When closing a window there is a chance that deleting a scrollbar
            triggers a GUI resize, which uses the window while it is not in a
            valid state.
Solution:   Set the buffer pointer to NULL to be able to detect the invalid
            situation.  Fix a few places that used the buffer pointer
            incorrectly.

Problem:    Auto-loading a function while editing the command line causes
            scrolling up the display.
Solution:   Don't set msg_scroll when defining a function and the user is not
            typing. (Yasuhiro Matsumoto)

Problem:    Strawberry Perl doesn't work on MS-Windows.
Solution:   Use xsubpp if needed. (Yasuhiro Matsumoto)

Problem:    Compilation error.
Solution:   Correct return type from int to pid_t. (Danek Duvall)

Problem:    Test 19 fails without 'smartindent' and +eval.
Solution:   Don't use ":exe". Source small.vim.

Problem:    When 'smartindent' and 'copyindent' are set a Tab is used even
            though 'expandtab' is set.
Solution:   Do not insert Tabs. Add a test. (Christian Brabandt)

Problem:    Python doesn't parse multi-byte argument correctly.
Solution:   Use "t" instead of "s". (lilydjwg)

Problem:    Source code not in Vim style.
Solution:   Adjust the style. (Elias Diem)

Problem:    Built-in colors are different from rgb.txt.
Solution:   Adjust the color values. (Benjamin Haskell)

Problem:    Can't load Perl 5.14 dynamically.
Solution:   Add code in #ifdefs. (Charles Cooper)

Problem:    When writing to an external command a zombie process may be left
            behind.
Solution:   Wait on the process. (James Vega)

Problem:    When filtering text with an external command Vim may not read all
            the output.
Solution:   When select() is interrupted loop and try again. (James Vega)

Problem:    Patch 289 causes more problems than it solves.
Solution:   Rever the patch untill a better solution is found.

Problem:    MSVC compiler has a problem with non-ASCII characters.
Solution:   Avoid non-ASCII characters. (Hong Xu)

Problem:    Crash when using fold markers and selecting a visual block that
            includes a folded line and goes to end of line. (Sam Lidder)
Solution:   Check for the column to be MAXCOL. (James Vega)

Problem:    Configure doesn't work properly with Python3.
Solution:   Put -ldl before $LDFLAGS. Add PY3_NO_RTLD_GLOBAL. (Roland
            Puntaier)

Problem:    When a BufWriteCmd autocommand resets 'modified' this doesn't
            change older buffer states to be marked as 'modified' like
            ":write" does.  (Yukihiro Nakadaira)
Solution:   When the BufWriteCmd resets 'modified' then adjust the undo
            information like ":write" does.

Problem:    Complete function isn't called when the leader changed.
Solution:   Call ins_compl_restart() when the leader changed.  (Taro Muraoka)

Problem:    has('python') may give an error message for not being able to load
            the library after using python3.
Solution:   Only give the error when the verbose argument is true.

Problem:    Can't compile with MSVC and tiny options.
Solution:   Move variables and #ifdefs. (Sergey Khorev)

Problem:    Crash when using "zd" on a large number of folds. (Sam King)
Solution:   Recompute pointer after reallocating array.  Move fewer entries
            when making room.

Problem:    Mapping <Char-123> no longer works.
Solution:   Properly check for "char-".  Add a test for it.

Problem:    The str2special() function doesn't handle multi-byte characters
            properly.
Solution:   Recognize multi-byte characters. (partly by Vladimir Vichniakov)

Problem:    An expression mapping with a multi-byte character containing a
            0x80 byte gets messed up. (ZyX)
Solution:   Unescape the expression before evaluating it (Yukihiro Nakadaira)
