O, fun. python, tcl and shellstring escapes...

OK, this part should work.

OK, adding argument names makes sense.  () and [] seems to match.  But
then...  You are using a python "raw string literal". So no escape
sequences nside the " quotes. But still a double \ because one will be
eaten by the shell?

I must admit I don't fully know what you are expecting at the shell
level or how precicely this comes out. Sorry.

Cheers,
