annotate mercurial/httprangereader.py @ 4668:e241598e956f

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove useless variable assignments in util.opener. The original idea might have been to prevent circular references, but as this assignment would have created another reference, this makes no difference.
