I don't oppose strict checking for only a pair of ( and ) because
a situation with (...] is extremely rare and usually means that
there is some bug.  So in reality there is no problem with
checking against the `insert-pair-alist' list.

What I care about is simplicity.  It should be easy for the user
to understand and remember what the command `delete-pair' does.
Failing on a non-pair character would be natural for a command
that is a counterpart of `insert-pair'.
