Multiple level undo/redo for Mercurial
hg-multiundo supports multiple levels of undo and redo for any Mercurial operation.  The extension provides two commands: hg undo and hg redo for undoing a change and redoing it, respectively.
hg-multiundo is configured in the multiundo section. The configuration elements that are used are:
- The level of undo states being maintained. hg-multiundo will save the last undocount states on disk to undo/redo.
The undo/redo state is hooked into Mercurial's opener, which Mercurial internally uses for all its file read/writes and using that we can discriminate what files to back up before a change is written to it.
All the undo state files are saved inside .hg/multiundo/ directory. The undo files are not meant to be edited by hand, but only through the use of the undo and redo commands.
- The purge extension does not use Mercurial's opener concept as a file system entry point, so any use of hg purge will not be undo-able.
