[mc] regex/wildcard in mc.ext

[Fourhundred Thecat]

Hello,

what type of regex/wildcard can I use in mc.ext ?

I have this for JPEG:

   type/^JPEG image data
	Include=image

Instead of creatin same rule for every image format:

   GIF image data
   JPEG image data
   ...

can I use some regex to match anything starting with:

   ^ONE_WORD image data

?

thank you
