Problem: Vim can create a directory but not delete it.
Solution: Add an argument to delete() to make it possible to delete a
directory, also recursively.
Problem: Need several lines to verify a command produces an error.
Solution: Add assert_fails(). (suggested by Nikolay Pavlov)
Make the quickfix alloc test actually work.
Problem: It is not possible to test code that is only reached when memory
allocation fails.
Solution: Add the alloc_fail() function. Try it out with :vimgrep.
Problem: g-CTRL-G shows the word count, but there is no way to get the word
count in a script.
Solution: Add the wordcount() function. (Christian Brabandt)
Problem: searchpos() always starts searching in the first column, which is
not what some people expect. (Brett Stahlman)

Solution: Add the runtest script to the list of distributed files.
Add the new functions to the function overview.
Rename the functions to match Vim function style.
Move undolevels testing into a new style test script.
Problem: Writing tests for Vim script is hard.
Solution: Add assertEqual(), assertFalse() and assertTrue() functions. Add
the v:errors variable. Add the runtest script. Add a first new
style test script.
Problem: When using the CompleteDone autocommand event it's difficult to
get to the completed items.

Solution: Make the value reflect whether search highlighting is actually
displayed. (Christian Brabandt)

be echoed and messes up the display. (Jacob Niehus)

Problem: Text drawing on newer MS-Windows systems is suboptimal. Some
multi-byte characters are not displayed, even though the same font
in Notepad can display them. (Srinath Avadhanula)

Muraoka)
