annotate abcfield.py @ 326:27f29e8aafea

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add --contains flag to abcfield.py. Currently we rely on any N: field with a Change: subnotice being the first N: field. Add --contains field to abcfield.py to remove this restriction. Also use it to extract new subfield Credit: and add that if present to the tune information in print and on web.
