Seems okay, but isn't it too obscure that prefixing with ' ' is the fast way of querying? Instead, maybe we can make lookup() to not search slow labels assuming these labeling schemes didn't exist in pre-revset era. Alternatively, we could add a config knob to switch off the old-style range support. _______________________________________________ Mercurial-devel mailing list Mercurial-devel@mercurial-scm.org https://www.mercurial-scm.org/mailman/listinfo/mercurial-devel
