So, I've got a gitconfig template for new people (also what link to as my ~/.gitconfig) so I have a smudge/clean:
[filter "gitconfig-rmuser"] clean = sed -e \"s/^\\( *email =\\).*/\\1 <email address>/\" -e \"s/^\\( *name =\\).*/\\1 <real name>/\" -e \"s/^\\( *signingkey =\\).*/\\1 <gpg key>/\" smudge = egrep \"^ *(email|name|signingkey) = \"
and .gitattributes: * filter=ident-line gitconfig filter=gitconfig-rmuser
However, it didn't filter/change my name/email/signingkey. Any ideas?
