Description of problem:
If the user types Ctrl-\ at the guestfish prompt, guestfish will immediately abort:

Welcome to guestfish, the libguestfs filesystem interactive shell for
editing virtual machine filesystems.

Type: 'help' for help with commands
      'quit' to quit the shell

><fs> sh: line 1: 21525 Quit                    guestfish $a

While this key combination is apparently intended to cause the process which currently has control of the terminal to abort, this is surprising behaviour in an interactive shell. I suggest it should be ignored.

Version-Release number of selected component (if applicable):
libguestfs-1.2.7-1.el5.1
