Problem: With 'autochdir' win_execute() can corrupt the buffer name,
causing :write to use wrong path.
Solution: Save and restore b_fname when 'autochdir' is active
(Ingo Karkat).
This is caused by a bad interaction of the 'autochdir' behavior,
overriding of the current directory via :lchdir, and the temporary
window switching done by win_execute(), manifesting when e.g. a custom
completion inspects other buffers:
1. In the initial state after the :lcd .. we have curbuf->b_fname =
"Xsubdir/file".
2. do_autochdir() is invoked, temporarily undoing the :lcd .., changing
back into the Xsubdir/ subdirectory.
3. win_execute() switches windows, triggering win_enter_ext() →
win_fix_current_dir() → shorten_fnames(TRUE)
4. shorten_fnames() processes *all* buffers
5. shorten_buf_fname() makes the filename relative to the current
(wrong) directory; b_fname becomes "file" instead of "Xsubdir/file"
6. Directory restoration correctly restores working directory via
mch_chdir() (skipping a second do_autochdir() invocation because
apply_acd is FALSE), but b_fname remains corrupted, with the
"Xsubdir/" part missing.
7. expand("%:p") (and commands like :write) continue to use the
corrupted filename, resolving to a wrong path that's missing the
"Xsubdir/" part.
To fix the problem the short filename is saved if its in effect (i.e.
pointed to by curbuf->b_fname) and 'autochdir' happened. It's then
restored in case of a local cwd override. The conditions limit this
workaround to when 'autochdir' is active *and* overridden by a :lchdir.

Problem: Test_cd_completion test fails in Appveyor. In Appveyor, a path
containing spaces was selected as the test target. But the
comparison failed because spaces were not taken into account
(after v9.1.2050)
Solution: Escape spaces in paths for comparison (Muraoka Taro)

Problem: tests: Test_cd_completion() may fail depending on the contents
of the root directory of the current drive on Windows.
readdir() may return a directory that cannot "cd" to, causing
this test to fail. An example of such a directory is
"System Volume Information" which only admin can "cd" to.
Solution: When determining the directory to use for testing, use the
directory that we actually "cd" to successfully.
In addition, directories with '$' in their names are also
excluded, as they are considered environment variables during
completion and do not work as expected.
Example: "$RECYCLE.BIN" (Muraoka Taro).

Problem: File paths change from symlink to target path after :cd command
when editing files through symbolic links
Solution: Add "~" flag to 'cpoptions' to control symlink resolution.
When not included (default), symlinks are resolved maintaining
backward compatibility. When included, symlinks are preserved
providing the improved behavior. (glepnir)

Problem: Manually deleting temp test files.
Solution: Use the 'D' flag of writefile() and mkdir().

Problem: Using common name in tests leads to flaky tests.
Solution: Rename files and directories to be more specific.
