@ -11385,13 +11385,9 @@ If an unhandled error happens in running this hook,
the function in which the error occurred is unconditionally removed, since
otherwise the error might happen repeatedly and make Emacs nonfunctional.
It is usually a bad idea to use this hook for expensive processing.
If unavoidable, `while-no-input' can be used avoid making Emacs
unresponsive while the user types. Furthermore, this hook is run
before redisplay, so the effect of the executed command won't be
displayed on the buffer until after the hook has finished (giving the
impression that Emacs is hanging). You can call `redisplay' inside
`while-no-input' to avoid this.
It is a bad idea to use this hook for expensive processing. If
unavoidable, wrap your code in `(while-no-input (redisplay) CODE)' to
avoid making Emacs unresponsive while the user types.
