annotate rhodecode/controllers/search.py @ 3485:b19b1723ff10 beta

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
pullrequest: pullrequest from changelog view It seems like it didn't work ... perhaps because I broke it. But now we clean it up and make it work: Use rev_end as the revision to merge. We don't know where to merge ... but start_rev cannot be used for that. This might to some extent have been working before ... but we prefer to clean it up and start over again when the normal merge workflow is fully working.
