[ale] Python & pexpect problem

[Alex LeDonne]

Jay-

I suspect the problem is that the command you give to spawn() doesn't
go through a shell, so the * file glob doesn't work - it's just a
literal splat character.

I think for the "else" case, you'll to build the list of the files in
python, so the command you spawn ends up looking like

scp file1.htm file2.htm file3.htm ... scp_to
