from FreeBSD, who earlier had obtained it from dash (Herbert Xu).
While doing the import, I cleaned up the sources (changed some file names
to avoid requiring a clean build, or signifigant surgery to the obj
directories if "build.sh -u" was to be used - "build.sh -u" should work
fine as it is now) removed some dashisms, applied some KNF, ...
