filemerge: in ':prompt', use ':fail' tool rather than returning directly The ':fail' tool now knows to write out the changed side for change/delete conflicts. This has no impact right now but will make things better when we move change/delete conflicts in here.

filemerge: in ':fail' tool, write out other side if local side is deleted We do this because we don't want to modify the dirstate for failures, and don't just want to leave the file missing from disk. Plus it's more useful for the user if the changed side is written out -- it is easier to delete a file than to get it back via hg revert.

mergestate: explicitly forget 'dc' conflicts where the deleted side is picked Once we move change/delete conflicts into the resolve phase, a 'dc' file might first be resolved by picking the other side, then later be resolved by picking the local side. For this transition we want to make sure that the file goes back to not being in the dirstate. This has no impact on conflicts during the initial merge.

merge.applyupdates: add all actions returned from merge state At the moment this is a no-op (the only actions defined are 'r', 'a' and 'g'), but soon we're going to add other sorts of actions to the dictionary returned from mergestate.actions().

identify: refer to log to be able to view full hashes

log: add 'hg log' example for full hashes

backout: add examples to clarify basic usage
