I made up a more thorough regression test for date input formats, and
found that there were still some cases that were rejected :-(. Attached
is a more complete patch that handles all month-name cases, and
explicitly can not change the behavior when there's not a textual month
name. Documentation addition and regression test included.
I'd like some further review of this before I risk applying it to 7.4
though ... anyone have time today?
