[PATCH v6 01/10] t0027: Make more reliable

From: Torsten Bögershausen <redacted>

Make the commit_chk_wrnNNO test in t0027 more reliable:
When the attributes of a commited file are changed and the file is otherwise
unchanged, Git may not detect that the next commit may need to treat the
file as changed.
This happens when lstat() doesn't detect a change, since neither inode,
mtime nor size are changed.

Add a singe "Z" character to change the file size.
Ignore it when comparing the files later.

 Changes since v5:
 - send the whole series, now 10/10
 - Removed the "will change in future" in one commit msg
 - Don't leak the filer in 4/10
