So let's read this (prog-widen):
" ... to remove any restrictions
imposed by the mode’s indentation engine and restore the
restrictions recorded in ‘prog-indentation-context’. This prevents
the indentation engine of a sub-mode from inadvertently operating
on text outside of the chunk it was supposed to indent, and
preserves the restriction imposed by the superior mode. When no
superior mode is in effect, this function just calls ‘widen’.
"
Don't see in which way this should be better. It lays the burden of
dealing with the mode in place into prog-mode. IMO wrong place, wrong
direction.
Expect prog-mode do deliver very basic things common to all programming
modes. Not dealing with and fixing special needs there.
Modes must meet the specific languages. Prog-mode must not be specific
and not provide tools for storing things like indentation-context. Let
the modes indent, fontify and jump around like they want - not thwarting
their settings seems all needed here.
