Doc tweak: accept -A as an alias for -a but don't try to explain it.

The help text tries to answer the questions "what does this command
do and how do I use it". Toybox silently accepts a lot of compatibility
flags like patch -u that aren't in the help text to let it run existing
scripts, but skips documenting them if doing so wouldn't doesn't help
write NEW scripts.
