Re: [9fans] Command to set samterm label

[umbraticus@prosimetrum.com]

Sorry, didn't mean to come off as insisting you had to do it
my way (I am guilty of hacking all kinds of things into my
own samterm); just wanted to point out there are other ways
besides adding a new command to sam.

There is a patch for this floating around somewhere: perhaps
whoever wrote it can chime in.

Below is a quick illustration of the other thought I had,
having label reflect the most recently topped buffer, in
case you are or anyone else is interested.
