This is up for discussion.
First of all, I am surprised to know that shell allows splitting
literals across a line (never tried it before), which is illegal in
I effectively treated the newline escape as a space, when joining
lines. Keeping the newline escape does not solve the problem as a raw
string is passed to _ip.system(). For example _ip.system("ls
/home/\\\nkrishna") would work but not _ip.system(r"ls
/home/\\\nkrishna"). As you are well aware we need to pass raw input
to correctly handle, among other things,
Currently I can't think of any solution, except resorting to not using
such esoteric commands.
