bug#23177: Inserting $ with delete-selection-mode set |

I just added the line
(put 'TeX-insert-dollar 'delete-selection (lambda () (null
TeX-electric-math)))
to git version of AUCTeX
(http://git.savannah.gnu.org/gitweb/?p=auctex.git;a=commitdiff;h=da88a3eca3107372131aa26930e548c039fe1b51).
Now `delete-selection' behavior is dynamically determined by
`TeX-electric-math' and should always do the-right-thing™. Thanks for
the suggestion.
Bye,
Mosè
