just-one-space

[Paul Pogonyshev <pogonyshev@gmx.net>]

Hi,

Would it be a good enhancement if that function could also optionally
delete newlines around point, based on a customizable variable?  Same
could also apply to `delete-horizontal-space', probably, but its name
insists on current behaviour.

	* simple.el (just-one-space-also-eat-newlines): New custom option.
	(just-one-space): Also delete newlines if
	`just-one-space-also-eat-newlines' is non-nil.
