Be consistent about upper versus lower case. (Upper seems to have the
majority, so I went with that, though I'm happy to provide the opposite
patch as long as we're consistent!)
Be consistent about using \t. (Though saving a few bytes seems like it
might be better done in the code that generates help.h rather than
directly in the source, since tabs make careful ASCII art layout hard
enough that we regularly have things misaligned.)
Remove trailing periods (most of which seem to have been added by me).
Always use the US "human readable" rather than my British
"human-readable", and be more consistent about declaring whether we're
showing multiples of 1000 or 1024.
Just say "verbose" rather than adding a useless "mode" or "output".

AOSP doesn't need -a specifically, but since it's needed for -s we may
as well accept it too.

When passed an empty string, glibc's basename() returns a pointer to the
string "." in read-only memory. If an empty suffix is given, it fits
the condition of being shorter than the path, so we try to overwrite the
null byte and crash. Fix this by just ignoring empty suffixes; they
don't do anything anyway.

Now that the kernel's 128k environment size has been lifted, it might be
possible to feed in a gigabyte of suffix so argv[2] is enough larger than
argv[1] that char *s decrements past NULL and points to arbitrary high
memory (I.E. strlen(suffix) > (long)base), at which point the base > s
test is defeated and we strcmp() against a wild pointer.
Which is read only anyway and on 64 bit you probably couldn't hit any
interesting addresses, but the fix is easy enough: compare strlen values
instead of pointers. So do that instead.

right in years (ubuntu broke its' vim implementation). Remove trailing spaces. Add/remove blank lines. Re-wordwrap in places. Update documentation with new coding style.
The actual code should be the same afterward, this is just cosmetic refactoring.
