'git for-each-ref --format=%(subject)' currently returns an empty string
if the log message does not contain a newline.
This patch teaches 'git for-each-ref' to return the entire log message
(instead of an empty string) if there is no newline in the log message.

Normally, log messages in git have trailing newlines. However, it seems the
"tag fixup commits" manufactured by cvs2svn/cvs2git (via git-fast-import)
have single-line log message without trailing newlines.
I have checked the other callers of copy_line(), and AFAICS they are not
affected by this change, since that would violate the git object format.
Have fun! :)
