From 6af44d2fa0cdcba11368cf4eee141e42bf0dd422 Mon Sep 17 00:00:00 2001
From: Alexander Polakov <polachok@gmail.com>
Date: Sun, 29 May 2011 14:55:46 +0400
Subject: [PATCH 1/8] ksh/vi mode: complete as command on Ctrl-f.
* adds a flag for x_cf_glob() to force completion like it was a command
* new argument for complete_word() to pass the flag
* reuse print_expansions() unused argument to pass the flag
Why: useful for sudo or one-liner completion
XXX: use different key combination?
