I see that ido implements it by turning "abc" into the regexp
".*a.*b.*c".  But matching this regexp against a string like
"abababababab" takes time O(N^3) where N is the length of the completion
candidate, which makes me a bit uneasy (and in general matching
"flex"ibly an input string of size M against a completion candidate of
size N can take time O(N^M)).  But I guess experience shows it's not
a real problem.

It should be pretty easy to add it as a new completion-style (after all
you can already get the same result with partial completion by typing
"*a*b*c").
