So much the wrong solution. First of all, I don't think that Linus is
on the bash development team so he can't help there. Also, bash is not
the only shell in the world. And, Linux is not the only operating
system in the world. There are still a lot of Unix systems (the system
that Linux is a clone of) out there. FreeBSD, NetBSD, Solaris, Mac
OSX, etc. You can't expect all of them to bend over backwards for
every Windows wart out there.
I don't run Windows myself so I can't test it but doesn't Python on
Windows work fine with Unix style EOL? So why not strip out the CR and
run the same file everywhere?
