0ef64bdb40 *: make GNU licensing statement forms more regular
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

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!

The tar -x command in busybox does not restore the file mode correctly.

The reason is most probably this code in
archival/libunarachive/data_extract_all.c:

       chmod(file_header->name, file_header->mode);
       chown(file_header->name, file_header->uid, file_header->gid);

chown clears the set*id bits (on current versions of linux :). Flipping
the order around fixes the problem.

(tested with 1.00pre3 from cvs).
