commit 42302658705e3545471f2f4e53c2f758355a2bcc
Author: Freddy Vulto <fvulto at gmail.com>

Fix completion of filenames containing colon.
This fixes the auto tests for `finger' and `ssh' on machines where an IPv6 host
"::1" is mentioned in /etc/hosts.
Added helper function __ltrim_colon_completions.
To run the tests:
./runCompletion finger.exp ssh.exp
