Problem: The script to check translations fails if there is more than one
NL in one line.
Solution: Count the number of NL characters. Make count() accept a string.
Problem: shellescape() always escapes a newline, which does not work with
some shells. (Harm te Hennepe)
Solution: Only escape a newline when the "special" argument is non-zero.
(Christian Brabandt, closes#1590)
Problem: Saving the redo buffer only works one time, resulting in the "."
command not working well for a function call inside another
function call. (Ingo Karkat)
Solution: Save the redo buffer at every user function call. (closes#1619)
Problem: Not all windows commands are tested.
Solution: Add more tests for windows commands. (Dominique Pelle,
closes#1575) Run test_autocmd separately, it interferes with
other tests. Fix tests that depended on side effects.
Problem: The return value of mode() does not indicate that completion is
active in Replace and Insert mode. (Zhen-Huan (Kenny) Hu)
Solution: Add "c" or "x" for two kinds of completion. (Yegappan Lakshmanan,
closes#1397) Test some more modes.
Problem: When making a character lower case with tolower() changes the byte
cound, it is not made lower case.
Solution: Add strlow_save(). (Dominique Pelle, closes#1406)
Problem: str2nr() and str2float() do not always work with negative values.
Solution: Be more flexible about handling signs. (LemonBoy, closes#1332)
Add more tests.
