This patch fixes a bunch of small problems in the descriptions of
-fisolate-erroneous-paths-dereference and
-fisolate-erroneous-paths-attribute:
* "which"/"that" confusion
* use American spelling of "behavior" vs British "behaviour"
* most places in the manual use "null" or more rarely "@code{NULL}"
rather than "NULL"
* wrong markup on option
I also added a note that -fisolate-erroneous-paths-dereference is
enabled by default at -O2 since it seemed odd to mention only that the
other option is *not* enabled.
Committed under the obvious fix rule, since this is more boring
tech-writer stuff.
