24.1; completing-read when COLLECTION has exactly one element |
|

Suggestion:
If the arg COLLECTION of completing-read is a list with exactly one
element and REQUIRE-MATCH is t, it can be quite redundant to go via
the minibuffer. Would it make sense if in such a case
completing-read could skip the minibuffer completely and simply
return the car of COLLECTION?
The specific situation that made me think about this was the command
ibuffer-switch-to-saved-filter-groups when
ibuffer-saved-filter-groups is a list with one element. Of course,
the surrounding code could also shortcut the call of completing-read
in such a case. But completing-read is possibly the better place to
implement such a behavior, say via a particular value of
REQUIRE-MATCH.
