annotate mercurial/archival.py @ 18507:c795c9f87792 stable

histedit: prevent parent guessed via --outgoing from being a revset (issue3770) If the binary hash of the parent node guessed via --outgoing happened to contain a special revset character (":" was specified in the bug), the revset parser would abort. Hexlifying the node before passing it to the revsingle call should fix that.
