hgk: fix tag list parser (issue4101)
As tags may have embedded spaces, and "hg tags" command doesn't escape them,
the output of the command doesn't make a well-formed list, so we can't just
iterate over it. Instead, apply a simple regexp to transform it to a list
which we actually use. Line boundary matching should be enabled.
