`make reinstall' won't install docs into wrong place.
Noticed by: obrien
(Closing PR #2132.)
Also some modification to change the makefile's install* targets to
do chown bin.bin on installed files.
(in that it doesn't depend on TeX). Lout produces regular
postscript for output. External postscript images/files can be
easily embedded in an Lout document.
