admin.texinfo, install.texinfo: Set edition to "b7-1"

admin.texinfo, install.texinfo: Set edition to "b7-1"

user-guide.texinfo: Set edition to "b7-1".  Fix the hoffset and
	voffsets for the included man page poscript files so that the images
	are lined up correctly (at least using MIT's dvips).

Makefile (user-guide): Make sure the kpasswd man page's postscript is
	built.  Add new target "clean-temp-ps" which cleans up the temporary
	postscript files.

man2ps: Changes to make man2ps more portable.  Remove bash specific
	constructs, and replace with calls to expr.  Since the arguments to
	"troff" require groff, just try to run groff explicitly (someone can
	always edit the ROFF and ROFF_OPTIONS at the top of the script).  Try
	to automatically detect whether csplit or gcsplit should be used, by
	grovelling through the user's path.

texinfo.tex: Check in version of texinfo.tex that has Jeff's magic
	doubleleft arrow hack.
