26.0.91; electric-pair-mode documentation |

When you turn on electric-pair-mode from emacs -q, then select a
region and type an opening delimeter like "(", the region is
surrounded by the "(" and ")" characters, the mark is deactivated, and
point is left after the opening delimeter. This should be documented.
(I searched for documentation but have not found any.)
Also, this functionality requires transient-mark-mode to be on. Are
there any equivalent "wrapping" commands for use when
transient-mark-mode is off? If not, maybe we should add some.

Thanks a lot for the improvement. With that, I'll close this bug.

"C-u C-x C-x" does work well enough, but Emacs normally also provides
commands that explicitly do some subset of what a region-aware command
would do in the same situation. For example, if you want to comment
out the region with transient-mark-mode switched off, you can either
type:
C-u C-x C-x [exchange-point-and-mark]
M-; [comment-dwim]
or more memorably, clearly, and without moving point,
M-x comment-region RET
I like having both options available, but the latter is preferable IMO.
Hence we could have some command that would be used like,
M-x wrap-region RET ( RET
to wrap a region explicitly.
