23.0.50; S-SPC remapped to C-@ for no good reason, severely reducing usability

23.0.50; S-SPC remapped to C-@ for no good reason, severely reducing usability

[Tim Van Holder]

Since yesterday morning's build, S-SPC seems to have been mapped to C-@
for no apparent reason; while C-SPC is a reasonable binding for
set-mark-command, S-SPC is not: it occurs very frequently when typing.
I now find myself having to frequently go back and re-add spaces to code
because they were eaten by S-SPC.

What's worse, I have no way of finding out where the mapping comes from.
C-h k S-SPC gives

  C-@ (translated from S-SPC) runs the command set-mark-command
    which is an interactive compiled Lisp function in `simple.el'.
  It is bound to C-SPC, C-@.

but it doesn't say where the translation comes from, and C-h b does not
list S-SPC as a translation, and only lists C-SPC and C-@ as bindings
for set-mark-command.

The translation seems to occur in all buffers, so it's probably some
global thing.

Should be fixed.
