If I can hazard to guess, some "#if PharoVM" were simply the
easiest/quickest way to deal with all the little divergences the
Pharo-non-OpenSmalltalkVM had accumulated, to efficently re-integrate with
OpenSmalltalkVM without getting caught up in discussions such as this.  My
initial concerns may have been over-enthusiastic at guessing at Pharo's
requirements.  While Esteban has been very busy ironing out the Pharo 6
release, maybe we can take from his lack of comment that the remaining
issue "--help showing only single-dashes" is not a big deal.

So lets integrate the PR (because there are some other good things in it,
and also its good to minimise the "#if PharoVM"s ).  Part of Pharo
philosophy to facilitate moving forward is that mistakes are okay.  Its
only a mistake if someone complains, and its then easy to add double-dash
to help message.  I wouldn't expect the permissive single+double dash in
actual options to be any problem.
