Problem:    ":func Foo" does not show attributes.
Solution:   Add "abort", "dict" and "range". (Yasuhiro Matsumoto)

Problem:    Compiler warning for unused argument.
Solution:   Add UNUSED.

Problem:    Running test 49 takes a long time.
Solution:   Don't have it grep all files.

Problem:    New regexp engine is a bit slow.
Solution:   Skip ahead to a character that must match.  Don't try matching a
            "^" patter past the start of line.

Problem:    Crash when debugging regexp.
Solution:   Do not try to dump subexpr that were not set.  Skip over count of
            \% items.

Problem:    New regexp engine is a bit slow.
Solution:   Do not clear the state list.  Don't copy syntax submatches when
            not used.

Problem:    Can't build with anything but huge features.
Solution:   Check for FEAT_PROFILE. (Yasuhiro Matsumoto)

Problem:    Can't see what pattern in syntax highlighting is slow.
Solution:   Add the ":syntime" command.

Problem:    Now that the NFA engine handles everything every failure is a
            syntax error.
Solution:   Remove the syntax_error flag.

Problem:    No error for using empty \%[].
Solution:   Give error message.

Problem:    Compiler warning for unitialized variable. (Tony Mechelynck)
Solution:   Assign something to the variable.

Problem:    Error for using \%V in a pattern in tiny Vim.
Solution:   Allow using \%V but never match. (Dominique Pelle)

Problem:    Python: Crash on MS-Windows when os.fchdir() is not available.
Solution:   Check for _chdir to be NULL. (Ken Takata)

Problem:    Can't build tiny Vim on MS-Windows.
Solution:   Adjust #ifdef around using modif_fname(). (Mike Williams)

Problem:    New regexp engine: \%> not supported.
Solution:   Implement \%>.

Problem:    New regexp engine: adding states that are not used.
Solution:   Don't add the states.

Problem:    Crash when regexp logging is enabled.
Solution:   Avoid using NULL pointers. Advance over count argument.

Problem:    Flags in 'cpo' are search for several times.
Solution:   Store the result and re-use the flags.

Problem:    Match failure rate is not very specific.
Solution:   Tune the failure rate for match items.

Problem:    New regexp engine: \%[abc] not supported.
Solution:   Implement \%[abc].  Add tests.

Problem:    Can't build without Visual mode.
Solution:   Add #ifdefs.

Problem:    Many users don't like the cursor line number when 'relativenumber'
            is set.
Solution:   Have four combinations with 'number' and 'relativenumber'.
            (Christian Brabandt)

Problem:    Can't build without the syntax feature.
Solution:   Add #ifdefs. (Erik Falor)

Problem:    New regexp engine: \%'m not supported.
Solution:   Implement \%'m.  Add tests.

Problem:    New regexp engine: \%V not supported.
Solution:   Implement \%V.  Add tests.

Problem:    nfa_recognize_char_class() implementation is inefficient.
Solution:   Use bits in an int instead of chars in a string. (Dominique Pelle)

Problem:    New regexp matching: Using \@= and the like can be slow.
Solution:   Decide whether to first try matching the zero-wdith part or what
            follows, whatever is more likely to fail.

Problem:    Building on MS-Windows doesn't see changes in if_py_both.h.
Solution:   Add a dependency. (Ken Takata)

Problem:    Error message for os.fchdir() (Charles Peacech)
Solution:   Clear the error. (ZyX)

Problem:    Compiler warnings for unused variables.
Solution:   Put the variables inside #ifdef.

Problem:    New regexp engine: saving and restoring lastlist in the states
            takes a lot of time.
Solution:   Use a second lastlist value for the first recursive call.

Problem:    New regexp engine: too much code in one function.  Dead code.
Solution:   Move the recursive nfa_regmatch call to a separate function.
            Remove the dead code.

Problem:    New regexp engine does not handle "~".
Solution:   Add support for "~".

Problem:    New regexp engine: overhead in saving and restoring.
Solution:   Make saving and restoring list IDs faster.  Don't copy or check \z
            subexpressions when they are not used.

Problem:    Completion of ":py3do" and ":py3file" does not work after ":py3".
Solution:   Make completion work. (Taro Muraoka)

Problem:    Configure doesn't find Python 3 on Ubuntu 13.04.
Solution:   First try distutils.sysconfig. Also fix some indents.  (Ken
            Takata)

Problem:    Python: a few more memory problems.
Solution:   Add and remove Py_XDECREF(). (ZyX)

Problem:    Python: Changing directory with os.chdir() causes problems for
            Vim's notion of directories.
Solution:   Add vim.chdir() and vim.fchdir(). (ZyX)

Problem:    Python: Possible memory leaks
Solution:   Add Py_XDECREF() calls. (ZyX)
