comparison abcfield.py @ 581:760d0ae5acea

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Revise abcfield.py to recognise continuation fields. Also default to HTML entity output, and replace --contains with --starts, which does the same thing but checks only the start of the line and removes the matched item.
