(Btw. testing for the truth value of a style is done with -t (default
if style is unset: false) or -T (default: true).)

Well, I'd suggest the normal context with an empty tag as in
":completion:${curcontext}:". I have problems finding a good style
name myself (`show-only-list-if-only-one-alternate-match-and-no-normal-one'
is probably a tiny bit too long). Hm. Maybe something like
`show-single-alternate' or, probably better, `show-single-ignored'
(because they `come' from styles named like `ignored-patterns').

Or we name it `single-ignored' (yes, there must be a better name) and
enhace it: if it's set to `show' we use the above. If it's set to
`menu' we also add the string from the line in the alternate set (as
usual, with -S '', in it's own group, with a call to _description and
so on...) and start menu-completion (compstate[insert]=menu).

We should also do that before the test in line 83 which I changed some 
days ago so that the user-requested menu-style (especially if (s)he
selected menu-selection) is respected (and the test in line 83 should
be changed to make it be used if the style we are talking about is set 
to `menu' -- but not in normal completion if there is no or only one
match).


Bye
 Sven
