- scheme/sort/* added by hand (for some reason it wasn't merged in)
- currently, some READ-PARAGRAPH tests don't pass: apparently,
due to some problems with the regexp library.
- Changed the rule for scsh/scsh.image to make ./go work and added
install-scsh-image to set =scheme48 correctly in the installed version
- Added an additional run of ./configure to autogen to have a Makefile for the rest
