From 1bf6551e42c79a594689a356a9b14759d55f3cf5 Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Wed, 26 Mar 2008 10:47:09 -0500 Subject: filter-branch.sh: support nearly proper tag name filtering Add support for creating a new tag object and retaining the tag message, author, and date when rewriting tags. The gpg signature, if one exists, will be stripped. This adds nearly proper tag name filtering to filter-branch. Proper tag name filtering would include the ability to change the tagger, tag date, tag message, and _not_ strip a gpg signature if the tag did not change.
