Fixed markdown as per git conventions.
yet more git markdown madness
start 0.1.4
Skleletal mandoc file, build system support for man page
mandoc
A lot of work on the man page and a bit on the build system.
progress on man page
Maybe the first sorta complete man page
Add missing .El
minor cleanups
Sadly, this is a jumbled/excremental changeset:

1. add more disk-grokking code but still not done
2. fix 64bit issues cleanly by using Perl to tell the build system the wordsize

I stupidly had not tested in i386 before but my -current box is i386
and sure enough my dumb '#if __amd64__' bit me in the ass.  This is
now handled by turning on -DOSDHUD_64BIT on machines where Perl's
$Config{longsize} is 8.

Only tested under OpenBSD 5.5 and 5.6-current (ca. 2014-12-04).
It is just %lu regardless, dumbass.
Cleanups
Fix up build system a bit more in prep for building an OpenBSD port

Add a simple configure script so I can set CONFIGURE_STYLE=simple
It links the appropriate make file to Makefile so you can just use
make normally, which makes packaging easier.

All GNU changes untested.
More build system futzing.

The simple configure script now understands a single option/argument:
--prefix=dir sets the installation prefix, which defaults to /usr/local.
It spits it into config.mk which is ephemeral and included by both
make-variant makefiles.  The make.sh script goes away now and the procedure
becomes more familiar:

  $ ./configure
  $ make
  $ sudo make install
Version 0.1.4, mainly to test packaging
Merge branch 'develop'

Releasing 0.1.4 to test out packaging
