mq: Parse commit message after we find start of changeset patch patch.extract extracts just the message below HG changeset patch. So to not parse comments above the patch, we reset the message if we find a changeset patch as we know the commit message comes after the changeset patch data. This is similar to the behavior of patch.extract. The drawback of this approach, after a qref -e the comment above HG changeset patch is gone. Without this patch the message would become part of the commit message in the HG changset patch part.

keyword: refactor kwdemo and make output translatable Better reflect the actual behaviour of the extension: - Make map arguments and -f/--rcfile not mutually exclusive but extend the current configuration - Map arguments and -f/--rcfile both override the defaults even when -d/--default is specified - -d/--default only overrides the current configuration Inform the user about extending/overriding behaviour, but only at the beginning; the following messages become terser, making the output translatable without too much code clutter. Rephrase help (use "short/long" option notation etc.).
