sgit -e 's/[[:space:]]$//g' '*Makefile'

At the request of Landon all Makefiles have had trailing spaces removed.
The request also included README.md files but this is more complicated
as some lines have to end in spaces in order to force line breaks. For
Makefiles it's fine though. Tested the Makefiles by doing 'make clobber
all everything' from the root directory and all appears to be fine. This
testing is important because depending on how this process (removal of
trailing spaces) was done it could break the Makefiles; for instance
trying something like:

    sgit -e 's/\s.*$//g' '*Makefile'

would rather break the Makefiles. This makes sense to anyone who knows
my script (and obviously sed :-) ) as long as they're not also tired but
I AM tired and so it was the first thing I tried (without thinking of
course ... though I had first thought of the correct way :-) ).

But what happens to the universes (yes I at least want to believe in the
multiverse theory and I hope it's true :-) ) when trailing spaces are
removed? :-)

As it turns out the only Makefiles touched were:

and most of them were my fault.
