annotate roundup/cgi/client.py @ 5073:d0aa596daca8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove 'import *' statement from cgi/client.py There are various 'import *' statements scattered through the code which are generally not a good thing. These should be fairly safe changes, but I'll commit them one file at a time to make it easier to track down issues with a bisect if they crop up later.
