revert 03c03172 "drop a commit right away if it matches an excluded commit"
This change resulted in a full history walk even when no objects will be added to the pack file. Fix this regression by reverting the change.
make 'got tag' unlock the work tree earlier when creating tags
The work tree was only held open in order to find its got.conf file since this file could contain a tagger name to use. Read the tagger name earlier. Once the tagger name is known we can close the work tree already.
make 'got cat' not search for a work tree if the -r option is used
Fixes failures in our test suite if 'got tag -l | less' is used in the work tree while cmdline tests are running.
