The short version of the message would also need to be fixed then, to
do that properly would require bigger changes in the return code of
bad_ref_char and the functions that call it. Then we could have e.g.:

    $ git checkout -b "I LOVE YOU"
    fatal: git checkout: Branch name cannot contain ' ';  marked by
<-- HERE in 'I ' <-- HERE

Similar to what you get from:

    $ perl -e '/I LOVE [/'

That would also make the long version unnecessary, and maybe improve
some other error messages that deal with ref names.
