Ok, here's the patch.
This allows selecting a specific style of a font and makes the -font option
treated the same in libass as in the osd, where it's already used as a
pattern. The patch also updates the manpage to make this clear.

It adds a treat_name_as_pattern boolean to all places needed to pass it from
ass_mp to ass_fontconfig, where it is checked and the pattern created
accordingly.

I've tested the patch with ass/srt subtitles as well as mkvs with embedded
fonts and everything seems to work fine.

Greetings
