logtoprocess: drop support for ui.log() call with invalid msg arguments (BC)
Before, the logtoprocess extension put a formatted message into $MSG1, and
its arguments to $MSG2... If the specified arguments couldn't be formatted
because of a caller bug, an unformatted message was passed in to $MSG1
instead of exploding. This behavior doesn't make sense.
Since I'm planning to formalize the ui.log() interface such that we'll no
longer have to extend the ui class, I want to remove any features not
conforming to the ui.log() API. So this patch removes the support for
ill-formed arguments, and $MSG{n} (where n > 1) parameters which seems
useless as long as the message can be formatted. The $MSG1 variable isn't
renamed for the maximum compatibility.
In future patches, a formatted msg will be passed to a processlogger object,
instead of overriding the ui.log() function.
.. bc::
The logtoprocess extension no longer supports invalid ``ui.log()``
arguments. A log message is always formatted and passed in to the
``$MSG1`` environment variable.
