narrowspec: replace one recursion-avoidance hack with another
When updating the working copy narrowspec, we call context.walk() in
order to find which files to update the working copy
with. context.walk() calls repo.narrowmatch(). In order to avoid
infinite recursion in this case, we have a hack that assigns the new
values for repo.narrowpats and repo._narrowmatch. However, doing that
of course breaks future invalidation of those properties (they're
@storecache'd). Let's instead avoid the infinite recursion by setting
a flag on the repo instance when we're updating the working copy.
