Problem: Git and hg see new files after running tests. (Manuel Ortega)
Solution: Add the generated file to .hgignore (or .gitignore). Delete the
resulting verbose file. (Christian Brabandt) Improve dependency
on opt_test.vim. Reset the 'more' option.
Problem: Characters below 256 that are not one byte are not always
recognized as word characters.
Solution: Make vim_iswordc() and vim_iswordp() work the same way. Add a test
for this. (Ozaki Kiichi)
Problem: After running the tests on MS-Windows many files differ from their
originals as they were checked out.
Solution: Use a temp directory for executing the tests. (Ken Takata, Taro
Muraoka)
Problem: Problems when building with Borland: st_mode is signed short;
can't build with Python; temp files not ignored by Mercurial;
building with DEBUG doesn't define _DEBUG.
Solution: Fix the problems. (Ken Takata)
Problem: Having auto/config.mk in the repository causes problems.
Solution: Remove auto/config.mk from the distribution. In the toplevel
Makefile copy it from the "dist" file.
Problem: Changing 'fileformat' and then using ":w" in an empty file sets
the 'modified' option.
Solution: In unchanged() don't ignore 'ff' for an empty file.
