Adding Keyword/Indentation

[gamename]

Hi,

I have a common in-house tcl construct that looks like this:

set args  {
    -argA  ANY
                DEFAULT xxx
}

This sets up a special argument of datatype ANY and has a default value
of xxx.

Setting the tcl mode to understand that ANY and DEFAULT are new
keywords is easy. But, how do I make tcl-mode indent DEFAULT to be,
say, 8 spaces after the same column as the beginning "-" in "-argA"?

TIA,
-T
