commands: don't infer repo for commands like update (issue2748) Maintain a whitelist of commands to infer the repo for instead. The whitelist contains those commands that take file(s) in the working dir as arguments.

hgweb: make the escape filter remove null characters (issue2567)

histedit: create obsolescence markers in deterministic order I arbitrary use the revnum of the precursor because it sound a right order.

bookmarks: when @ bookmark diverges, don't double the @ sign (BC) This changeset treats the bookmark "@" as a special case for the naming of divergent bookmarks, as per the tables below. For the <no alias> case, the actual suffix will vary, depending on what suffixes are already in use. Before: Bookmark | Remote | Divergent Bookmark -------------------------------------- foo | bar | foo@bar foo | <no alias> | foo@1 @ | bar | @@bar @ | <no alias> | @@1 After: Bookmark | Remote | Divergent Bookmark -------------------------------------- foo | bar | foo@bar foo | <no alias> | foo@1 @ | bar | @bar @ | <no alias> | @1 This case is likely to be more common now that 92980a8dfdfe has made the "@" bookmark have special meaning to clone. The change in behavior was discussed on the mailing list in the thread below: http://markmail.org/thread/rwedgxp7le5j2h2f

histedit: max(x, key=y) and min(x, key=y) are not available in python 2.4 Use sorted(x, key=y)[-1] or sorted(x, key=y)[0] instead.

vfs: use self.write to write symlink placeholders The existing write() path is much more robust than the hand-rolled version that was inlined here.

histedit: do not use "min" on ctx It does not crash but does not compare revision number at all. We actually remove any call to min because the list is already topologically sorted.

histedit: clean abort when there is nothing to edit

histedit: rename `revs` in `ctxs` inside the `between` function The variable content is actually contexts, not revision numbers.

test: fix invalid redirection for histedit text Appending to the file is wrong, we want new content.
