The commands that make use of --git-completion-helper feature could
now produce a lot of --no-xxx options that a command can take. This in
many case could nearly double the amount of completable options, using
more screen estate and also harder to search for the wanted option.

This patch attempts to mitigate that by collapsing extra --no-
options, the ones that are added by --git-completion-helper and not in
original struct option arrays. The "--no-..." option will be displayed
in this case to hint about more options, e.g.

" There's no magic numbers (previously we keep 3 --no- options)"

Here I see 3 no- options, is the number how many no's to show configurable now?
