branchmap: stop looking for stripped branch Since repoview in 2.5 we do not make special call to `branchmap` when stripping. We just recompute the branchmap from a lower subset that still has valid branchmap. So I'm dropping this dead code.

branchmap: remove the droppednodes logic It was unused. note how it is only extended if the list is empty. So it's always empty at the end. We could try to fix that, however this would part of the code is to be removed in the next changeset as we do not run `branchmap` on truncated repo since `repoview` in 2.5.

branchmap: fix blank line position The blank line was after was after the `if` condition instead of before.

histedit: add more detailed help about "--outgoing"

histedit: abort if there are multiple roots in "--outgoing" revisions Before this patch, if there are multiple roots in "--outgoing" revisions, result of "histedit --outgoing" depends on the parent of the working directory. It succeeds only when the parent of the working directory is a descendant of the oldest root in "--outgoing" revisions, and fails otherwise. It seems to be ambiguous and difficult for users. This patch makes "histedit --outgoing" abort if there are multiple roots in "--outgoing" revisions always.

hgweb: eliminate extra complexity in process_dates definition There was an extra anonymous outer function, called immediately. It is removed in this patch.
