A problem with this change is that it provides no way for the user
to override this setting (e.g. in case even 10 Mb is not enough).
It would be better to write that using the same approach as is
used for TMPDIR above, i.e.

	LINK=${LINK=/stack:10485760}   # 10 Mb

This way, the user can override this by just setting the LINK
environment variable, rather than having to modify the `ml' script.
