Here I use git symbolic-ref to update HEAD with a ref whose name
contains trailing newlines:
$ git symbolic-ref -m "this message does not appear" HEAD 'refs/heads/master
>
>
> '
The newlines are inserted into .git/HEAD, but are innocuous, because
other git commands ignore them. The bug is that the -m option is
completely ignored:
$ git reflog HEAD | grep 'message does not appear'
$
If trailing newlines are considered acceptable, the -m option should
be honored. If not, an error message should be printed and thecommand
should exit with a nonzero exit status.
I will prepare a patch if you will say which behavior would be
preferable.
