New Revision: 184188

URL: http://svn.digium.com/svn-view/asterisk?view=rev&rev=184188
Log:
Avoid destroying the CLI line when moving the cursor backward and trying to autocomplete.

When moving the cursor backward and pressing TAB to autocomplete, a NULL is put
in the line and we are loosing what we have already wrote after the actual
cursor position.

(closes issue #14373)
