Re: [9fans] Sam commands in acme

[hugo rivera <uair00@gmail.com>]

I tested the command you suggested (,x/\/\*/.,/\*\//) and it works as
I wanted, thanks. But there's something I still don't understand and
is the meaning of that comma in there. As far as I know, the comma is
a  mark that delimits the addresses that acme understands, but I do
not know how a comma is interpreted inside a regexp. I'd really
appreciate if you could clarify this matter to me.
