[TxMt] Edit special TextMate files

[Paul Williamson]

I am accustomed to using my text editor to peek at arbitrary files. 
TextMate is great for that, except when the file in question is a 
special TextMate file such as foo.tmLanguage or foo.tmCommand. I'd 
like to see a way to open these files as plain text. Or is there one 
I've missed?

Of course the command-line "mate" needs to support this too.
