annotate piecrust/processing/requirejs.py @ 550:6f216c1ab6b1

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
bake: Add a flag to know which record entries got collapsed from last run. This makes it possible to find entries for things that were actually baked during the current run, as opposed to skipped because they were "clean".
