The documentation is now fixed, including NEWS. There are 2 new
functions, forward-word-strictly and backward-word-strictly, that move
by words using only the syntax table and disregarding
find-word-boundary-function-table. I've reviewed all the users of
forward-word and backward-word, and made those of them which IMO
should not heed to the likes of subword-mode (there were quite a few)
use these new functions.
I didn't mark forward-word and backward-word interactive-only, as I
don't think this is needed, or even TRT, since the sub-word feature
explicitly wants to be honored in many word-related commands.
I therefore consider this bug "done".
As an aside, I don't understand how could we admit such pervasive
changes into our codebase without proper documentation and without
carefully considering its non-trivial implications.
I also think that the implementation of sub-word mode, which uses
find-word-boundary-function-table, is a kludge, and shouldn't have
been accepted in its present form. find-word-boundary-function-table
is a char-table, which should have made it crystal clear that
(ab)using it to have the same function called for _any_ character is
against the spirit of char-tables. This char-table was introduced for
script-specific word motion. Patches to fix this aspect of sub-word
mode will be very welcome (on master).
But all this is a ship that sailed long ago, sadly, so all we can do
is lick our wounds and hope not to make such mistakes in the future.
Thanks.
