Not requiring a third Tab to show the list of possible completions

Browse Source 
when the first Tab added the part that all matches have in common.

So now two Tabs in a row will always show the list of possible
completions -- if there /are/ any completions.  Which means that
a second Tab will either: 1) do nothing, when the name is complete
and exists; 2) beep, when nothing in the current directory starts
with the current string; 3) show the list of matches.

* src/files.c (input_tab): If the first Tab added the part that all
matches have in common, don't require a third Tab to show the list.

* src/search.c (get_history_completion): Avoid leaking memory
when tabbing on a string that does not occur in the history.
