Comment 4 for bug 123665

You're right. It seems to work when you're not using the bash-completion package. If you do however, then it's still broken.

I'm not sure yet wether it's a quoting problem or a genuine bug in bash:

mika@arthur:~/rrr(1)$ compgen -f "1\'"
1'2 2
1'1 1
mika@arthur:~/rrr$ compgen -f "1\'2"
mika@arthur:~/rrr(1)$ compgen -f "1\\'2"
mika@arthur:~/rrr(1)$ compgen -f "1\\\'2"
mika@arthur:~/rrr(1)$ compgen -f "1\\\\'2"
mika@arthur:~/rrr(1)$ compgen -f "1\\\\\'2"
1'2 2
