not halt on error. Thanks to Wolfram for reminding me. ;)
Also remove a unnecessary test for c == '\n', since the
loop (in ParseSkipLine) will not terminate unless
c == '\n' || c == EOF, and the EOF case is already
explicted handled by a return statement.
problems in the process:
1. Quoting should work properly now. In particular, Chet's reported bash
make problem has gone away.
2. A lot of memory that just wasn't being free'd after use is now freed.
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.
