Comment added on issue 165 pointing to specific tags that wrongly failed 
to get deleted.

Another comment added on issue 165 regarding cases where a tag deletion 
command deleted only a subset of the matching tags, since it seems 
plausible the underlying issue could be the same.

Issue 166 filed for the deleted-r branches and tags staying around.

Issue 167 filed for the loss of the changes from the commit for the 
gcc-2_95_3 tag.

In all cases, my testing includes changes from my merge requests for the 
gcc-conversion repository, rather than being based on the unmodified 
upstream state of that repository, but I don't have any reason to think 
these bugs depend on those changes.

A further note: in a previous run of the conversion I didn't see any 
emptycommit-* tags.  In my most recent conversion run, I see 4070 such 
tags.  How do I tell reposurgeon never to create such tags?  Or should I 
add a tag deletion command for them in gcc.lift, once tag deletion is 
working reliably?
