[TxMt] Creating a new scope for somecmd( )

[Jami Haavisto]

I was trying to do a new scope for being inside of a certain command  
parentheses
eg. trace( 'here is the new scope' ), so that I could do some special
tab triggers inside that scope, but I wasn't able to do it. I tried  
all kinds of
combinations for begin and end in the language grammar with no luck.
Apparently I somehow mess up the regular expression.

Can any of you help out ?
