revset: mask specific names for named() predicate
Before this patch, revset predicate "tag()" and "named('tags')" differ
from each other, because the former doesn't include "tip" but the
latter does.
For equivalence, "named('tags')" shouldn't include the revision
corresponded to "tip". But just removing "tip" from the "tags"
namespace causes breaking backward compatibility, even though "tip"
itself is planned to be eliminated, as mentioned below.
http://selenic.com/pipermail/mercurial-devel/2015-February/066157.html
To mask specific names ("tip" in this case) for "named()" predicate,
this patch introduces "deprecated" into "namespaces", and makes
"named()" predicate examine whether each names are masked by the
namespace, to which they belong.
"named()" will really work correctly after 3.3.1 (see
873eb5db89c8 for
detail), and fixing this on STABLE before 3.3.1 can prevent initial
users of "named()" from expecting "named('tags')" to include "tip".
It is reason why this patch is posted for STABLE, even though problem
itself isn't so serious.
This may have to be flagged as "(BC)", if applied on DEFAULT.
