comparison abcfield.py @ 122:295ba8275ab4

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Make output larger where possible. This is done by a) reducing the page margins b) compressing the heading and removing all but Notes: fields. The latter produced vertically smaller tune PDFs that will scale wider. In the process, modify abctitle.py to extract the first of any header field, and move formatting for a single tune into a .fmt file.
