[PATCH] git-name-rev: don't use printf without format

[René Scharfe <rene.scharfe@xxxxxxxxxxxxxx>]

printf() without an explicit format string is not a good coding practise,
unless the printed string is guaranteed to not contain percent signs.  While
fixing this, we might as well combine the calls to fwrite() and printf().
