revset: get revision number of each node from target namespaces
Before this patch, revset predicate "named()" uses each nodes gotten
from target namespaces directly.
This causes problems below:
- combination of other predicates doesn't work correctly, because
they assume that revisions are listed up in number
- "hg log" doesn't show any revisions for "named()" result, because:
- "changeset_printer" stores formatted output for each revisions
into dict with revision number (= ctx.rev()) as a key of them
- "changeset_printer.flush(rev)" writes stored output for
the specified revision, but
- "commands.log" invokes it with the node, gotten from "named()"
- "hg debugrevspec" shows nodes (= may be binary) directly
Difference between revset predicate "tag()" and "named('tags')" in
tests is fixed in subsequent patch.
