annotate hgext/hbisect.py @ 5483:0c43f87baba3 default tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix file-changed-to-dir and dir-to-file commits (issue660). Allow adding to dirstate files that clash with previously existing but marked for removal. Protect from reintroducing clashes by revert. This change doesn't address related issues with update. Current workaround is to do "clean" update by manually removing conflicting files/dirs from working directory.
