This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.

Erik - please apply.

Authors - please check that I didn't corrupt any meaning.

Package importers - see if any of these changes should be
passed to the upstream authors.

I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.

What is "pretect redefined for test" in cmdedit.c?

Good luck on the 1.00 release!
