Some Linux variants (Ubuntu, at least) symlinks /bin/dash instead of
/bin/bash to /bin/sh, which breaks the Makefile. The shell command
"read" needs a variable name in such cases.

* src/nb/Makefile

dummy variable.

Remove unnecessary TODO.

Correctly alphabetize list of contributors. Also add Chuck Toporek to
the editors list (he was our very very very first editor).
