Subject: add_keybinding: always allocate the new keybinding
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=8b534a13651f1416d368bcc10b496ca189c2ca0c;p=tig.git

add_keybinding: always allocate the new keybinding

Fixes infinite loop repoted by Miciah. Also simply continue when wgetch
returns ERR (-1) instead of calling get_keybinding() etc.
