make sane.ps generation more portable

Macport version of latex does not intall changebar
package referenced by sane.tex.

Commented out this reference since its not actually
used by any docs.  This should allow generating
with a wider range of latex versions.

Also added quotes around TEXINPUTS (where to find
our custom distributed html.sty) since OSX often
has spaces in path names.
