context: clarify that only one attempt is made to interpret changeid We can now tell what type of revision specifier we have just by looking at it (we no longer attempt to interpret it in one way after the other -- that's now in scmutil.revsymbol()). Let's clarify this in the code by swithing to if/elif. Differential Revision: https://phab.mercurial-scm.org/D3451

context: only bother looking for broken dirstate for 20-byte changeid If we fail to look up a changeid in changectx.__init__, we check if it exactly matches any of the dirstate parents, and if it does, we print a more specific message ("working directory has unknown parent '...'!" instead of "unknown revision '...'"). The dirstate parents are always 20 bytes, so there's no need to check for a match when the given changeid is not 20 bytes. (And now that all the other allowed forms of changeid have been moved out of the constructor, there's no risk that a changeid that did match a dirstate parent was actually a valid bookmark.)

revset: pass in lookup function to matchany() (issue5879) Silly mistake in f83cb91b052e.

test-hgweb: add test for foo-bar name lookup This is broken since f83cb91b052e "revset: pass in lookup function instead of repo (API)."
