Problem: Restoring directory after using another window is inefficient.
Solution: Only restore the directory for win_execute(). Apply 'autochdir'
only when needed.
Problem: Dec mouse test fails without gnome terminfo entry.
Solution: Check if there is a gnome entry. Also fix 'acd' test on
MS-Windows. (Dominique Pellé, closes#9282)
Problem: "verbose pwd" shows confusing info when :lcd does not change
directory.
Solution: Clear last_chdir_reason also when the directory does not change.
(closes#9160)
Problem: Various inconsistencies in test files.
Solution: Add modelines where they were missing. Use Check commands instead
of silently skipping over tests. Adjust indents and comments.
(Ken Takata, closes#6695)
Problem: No statistics displayed after running tests.
Solution: Summarize the test results. (Christian Brabandt, closes#4391)
Also make it possible to report a skipped file.
Problem: DirChanged is also triggered when the directory didn't change.
(Daniel Hahler)
Solution: Compare the current with the new directory. (closes#3697)
Problem: When a file gets a name when writing it 'acd' is not effective.
(Dan Church)
Solution: Invoke DO_AUTOCHDIR after writing the file. (Allen Haim, closes
#777, closes#803) Add test_autochdir() to enable 'acd' before
"starting" is reset.
