Correct.

Both the web build and the doc build honour the DESTDIR variable, with
DESTDIR taking precedence over DOCDIR.  So if you had DESTDIR set in the
environment to something like /usr/local/www/data/, that's where the
docs would get installed.

The "unset" builtin returns a non-zero exit value if the variable
doesn't exist in the environment.  This halted the build (and is the
reason why my first commit to this broke the build -- I tested it with
DESTDIR on the command line, which worked, rather than in the
environment, which failed).  Hence the '||' connector, rather than the
'&&' connector which I originally used.
