Most of the space-savings comes from not having to duplicate the C

that even work?), then this space-savings would be far less.
That's not entirely true. Some of the commands are from sash, and have
tons of 1:1 copied code to split them into separate commands, and I have
fixed that up; some other commands shared routines as well, and those
are also combined. The C library is not the only duplication waste
involved. Additionally, commands like "true" and "false" are so trivial
that their .c files were destroyed in favor of pushing their code into a
single line in busyelks.c. I have yet to merge the usage() calls
together, but I've already packed a lot of stuff into one executable,
and it works as expected using the elksemu command. Once I get some of
the ugliness fixed up, I'll push this to Git.
