(defmacro combine-after-change-calls (&rest body)
"Execute BODY, but don't call the after-change functions till the end.
If BODY makes changes in the buffer, they are recorded
and the functions on `after-change-functions' are called several times
when BODY is finished.
The return value is rthe value of the last form in BODY.
If `before-change-functions' is non-nil, then calls to the after-change
functions can't be deferred, so in that case this macro has no effect.
Do not alter `after-change-functions' or `before-change-functions'
in BODY."
