localrepo: don't reintroduce pruned tag entries when tagging

If a commit and a followup tag commit are pruned, there are no references to it
in any non obsolete version of .hgtags.  Without this change however, the next
time a tag is added to another branch, the obsolete references are appended in
.hgtags before the new entries for the current tag command.

The annotation to unfilter localrepo._tag() has been around since b3af182a1944.
The log message for it mentions computing the tag cache though, so I'm not sure
if this was misplaced?  It looks like branchmap was aware of filtering then, and
now tracks a cache per view.

Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:

It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:

Use the Makefile in this directory to generate the man and HTML pages.
