The problem with changing the substitution to prevent an infinite
number of matches is that it doesn't provide the necessary feedback
to the user that there's a bug in the/a makefile. Reporting the bug
without making the condition fatal makes the feedback mostly useless
due to the way that make fails to prefix the error with program name,
makefile file name and line number information.

to make beforedepend. This works fine without -n. The job to make
beforedepend has normally been started, and beforedepend is marked

except in main.c. I will be changing MAKEOBJDIR back to its old
behaviour so that the comment in main.c actually applies.
Removed irrelevant misformatted text about make's name being argv[0].

problems in the process:
1. Quoting should work properly now. In particular, Chet's reported bash
make problem has gone away.

This should cause make to take up a LOT less memory when dealing with
archive targets.
3. Give proper credit to Adam de Boor in a number of files.
