basename: fix segfault on null input; add tests
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.

Static analysis from Hyejin Kim found possible pointer underflow.
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.

Reindent to two spaces per level. Remove vi: directives that haven't worked 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.
