annotate roundup/rest.py @ 6354:b61de764c8cc

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Remove left over python style config remnant, doc update. Replace three with two as there are only two items in the list. Remove setting that was used in the code for python style init files. Support for python style init files removed a while ago and were deprecated in 0.8 timeframe IIRC.
