prevent log message loss of folded commits during histedit
If the histedit log message editor exits without saving its buffer,
Got threw away log messages of all commits which were folded. Only the
last commit message is preserved, which could be something meaningless
like "fixup".
Instead, preserve the initial editor buffer content as-is.
That is not going to be an ideal log message, but doesn't throw away
information and stands out visually because the newly created log message
will start with a comment like '# log message of folded commit a0ff...'
