subrepo: annotate addremove with @annotatesubrepoerror

histedit: don't recreate state object Previously, the histedit state object was being recreated during continue/abort. This meant that the locks that were held on the original state object were not available to actions, which meant actions could not release the lock on the repository (like an 'exec' action would need to do). This affected our internal extension that added the 'exec' action.

hgweb: clearly outline <tr> block in paper/changeset.tmpl This particular <tr> block should use the style of its neighboring blocks, otherwise it's easy to think that the closing '</tr>' is missing.
