[New-bugs-announce] [issue27528] Document that filterwarnings(message=...) matches the start of a message

[Martin Panter]

New submission from Martin Panter:

I assumed that the “message” parameter could be used to match any substring of a warning message, but it turns out it calls regex.match(), which is anchored at the beginning of the search string (but is not anchored at the end). I propose this patch to clarify the documentation, and add some tests.
