I finally succeeded in running an Emacs from July 2014. (Work was
required to make it run.) I was flabbergasted to find that it DID do
the lax whitespace search.
Has the feature been active for 3 years and I never noticed until now?
It looks that way.
I tried various cases and learned something that might explain
why I didn't notice it.
It seems that the feature applies only to SPC. Entering C-j matches
only newline. That seems to explain why my searches for C-j C-j
always worked as intended.
Given that in lax matching SPC matches any sequence of whitespace,
there is no sense in a lax SPC preceded or followed by another
whitespace character.
Thus I propose that SPC adjacent to some other whitespace character
should match only a single space. In particular C-j SPC should match
only newline space, and SPC SPC should match only space space.
What do people think of that?
Meanwhile, how about colorizing a space in the echo area when it is
being searched for laxly? That should help users understand what is
happening.
