been doing for the last couple days.

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 same bug exists in all versions of HUSH from BB v0.60.x up to and
including v1.00-pre9. The attached patch fixes this:

075dd81c44 Remove the CONFIG_FEATURE_SH_APPLETS_ALWAYS_WIN option. It was sortof 
stupid and didn't work properly anyways.

that still has running jobs.  Instead, we ignore it and expect
it to be cleaned by the background job stuff.

04407e522b Another hush update from Larry: 
Fixes the interaction between if/then/else/fi syntax and variables.
    I planned to do it right from the beginning, but my implementation
    was buggy.  Also adds the relevant test cases.  Also adds some old
    Matt Kraai variable test cases that got left out somehow.
