comparison piecrust/sources/posts.py @ 516:73bd408caebc

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
internal: Return `None` instead of raising an exception when finding pages. This makes the `posts` source behave like the other ones.
