[TxMt] Specify file language from command line

[Michael Twomey]

Hi,

Is there any way to specify the language of a file from the mate command?

I'm using mate in the middle of shell pipe lines so there isn't any
filename to pick up on.

The simplest example is "svn diff | mate". While I can set the
language to diff, that becomes the default for all piped in text, so
"cat README | mate" will use the diff language instead of plain text.

Am I missing something very obvious? (mate -h doesn't appear to show
anything relevant).

cheers,
  mick
