I can't image the "regex is matched in a "greedy" way" or ONIG_OPTION_GREEDY.
Is it different from a regex which does not include any non-greedy operators.
from oniguruma.
For example, in the string "2 km 1 km/h 5 km/h"
onig_search
with regex "[0-9]+[[:space:]](km|km/h)"
with ONIG_OPTION_NONE
finds three matches: "2 km", "1 km"
and "5 km"
, but with ONIG_OPTION_FIND_LONGEST
the matches become greedy: "1 km/h"
and "5 km/h"
.
It both makes group matches greedy, and only keeps the longest matches. This isn't logical that greediness of the group operator also changes, because some people might need to only get the longest matches, and some people might only need the greedy group operator, and this option does both at the same time.

It is too difficult to select the longest element in alternatives at runtime.
And as you know, alternative operator has priorities from the left to the right.
I think that'll be enough for many cases.
