bug#12297: show-paren-mode only recognizes show-paren-delay value on activation

Activating show-paren-mode sets the delay time to show-paren-delay
initially, but altering that value later has no effect. i.e., after:

(show-paren-mode)
(setq show-paren-delay 0)

The timer is still set to the original value .125, until the mode is
re-activated.
This should maybe be noted in the variable description, or there should be
a dedicated function to set the new value, e.g. by turning line 125 of
paren.el into a separate function:

(setq show-paren-idle-timer (run-with-idle-timer
                   show-paren-delay t
                   'show-paren-function))

OK, fixed in current trunk.
