localrepo: extend "changeid in repo" to return True for workingctx revision This is necessary to implement "wc" symbol for workingctx, that will be used as follows: $ hg annotate -r wc FILE In principle, "rev in repo" should be True if "repo[rev]" can return a context object. But when it was implemented by ea3acaae25bb, lookup() had a long logic to map all sorts of changeids to nodes, and "None in repo" did crash because lookup() could not accept None. So I assume that the case of changeid=None was not considered. Now "None in repo" doesn't crash, it should be True for workingctx revision. Behavior of "changeid in repo": revision "null" existing rev None (workingctx) ---------- ------ ------------ ----------------- original* True True TypeError current True True False this patch True True True (*original: ea3acaae25bb)
