Problem: Not enough testing for popup menu. CTRL-E does not always work
properly.
Solution: Add more tests. When using CTRL-E check if the popup menu is
visible. (Christian Brabandt)
Problem: A funccal is garbage collected while it can still be used.
Solution: Set copyID in all referenced functions. Do not list lambda
functions with ":function".
Problem: Using function() with a name will find another function when it is
redefined.
Solution: Add funcref(). Refer to lambda using a partial. Fix several
reference counting issues.
Problem: The short form of ":noswapfile" is ":noswap" instead of ":now".
(Kent Sibilev)
Solution: Only require three characters. Add a test for the short forms.
Problem: User defined functions can't be a closure.
Solution: Add the "closure" argument. Allow using :unlet on a bound
variable. (Yasuhiro Matsumoto, Ken Takata)
Problem: Deleting an augroup that still has autocmds does not give a
warning. The next defined augroup takes its place.
Solution: Give a warning and prevent the index being used for another group
name.
Problem: Loading defaults.vim with -C argument.
Solution: Don't load the defaults script with -C argument. Test sourcing
the defaults script. Set 'display' to "truncate".
Problem: getcompletion(.., 'dir') returns a match with trailing "*" when
there are no matches. (Chdiza)
Solution: Return an empty list when there are no matches. Add a trailing
slash to directories. (Yegappan Lakshmanan) Add tests for no
matches. (closes#947)
Problem: When there is an CmdUndefined autocmd then the error for a missing
command is E464 instead of E492. (Manuel Ortega)
Solution: Don't let the pointer be NULL.
Problem: "cgn" and "dgn" do not work correctly with a single character
match and the replacement includes the searched pattern. (John
Beckett)
Solution: If the match is found in the wrong column try in the next column.
Turn the test into new style. (Christian Brabandt)
Problem: Using submatch() in a lambda passed to substitute() is verbose.
Solution: Use a static list and pass it as an optional argument to the
function. Fix memory leak.
Problem: Using the system default encoding makes tests unpredictable.
Solution: Always use utf-8 or latin1 in the new style tests. Remove setting
encoding and scriptencoding where it is not needed.
Problem: filter() and map() either require a string or defining a function.
Solution: Support lambda, a short way to define a function that evaluates an
expression. (Yasuhiro Matsumoto, Ken Takata)
