The tag rewriting code used a 'sed' expression to substitute the new tag name into the corresponding field of the annotated tag object. But this is problematic if the tag name contains special characters. In particular, if the tag name contained a slash, then the 'sed' expression had a syntax error. We now protect against this by using 'printf' to assemble the tag header. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>
