The resulting patch is good, but "they never contain spaces" is not
a very good rationale. The real reason is that (1) we use them only
to hold a single token value (or leave them empty) in the current
code, and (2) if the feature they represent is enhanced in the
future to make them multi-token options (e.g. we may allow $jobs to
contain, in addition to "--jobs=2", "--jobs 2" for whatever reason
later), it is likely that we would want these multi-tokens split at
$IFS (e.g. "--jobs" and "2" get passed as separate option, not a
single "--jobs 2" string).

This is OK.
