Subject: lib-abbrev: Don't show a menu when not needed.
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=151c5d40575f2beb2caa6f15c2c2875f2a9c049a;p=edlib.git

lib-abbrev: Don't show a menu when not needed.

If there is only one match, just insert it, don't show a menu.

If all matches have a common prefix, just insert that.
