Re: [PATCH 2/2] filter-branch.sh: support nearly proper tag name filtering

Hi,

Add support for creating a new tag object and retaining the tag message,

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.

I think such a change in semantics merits a new option.  Maybe 
even something like

	"--rewrite-tags=(strip-signatures|redo-signatures|no-signed)"

or some such.  But maybe not; to rewrite a tag, you have to specify it 
explicitely (or implicitely with --all).

Ciao,
