Hello!
Again. I wondered if the following patches could do stuff.
scsh compiles/works now, but I really don't know if the following
replacements can be done for the existing macros.
Can they? I could not reproduce a situation where they are called, so.
I just don't know.
Please, tell me :-)
Unfortunately, Martin (maintainer) did not response.
Alex

I need a new ~/.sig.
