Commits 50cff52f1a (When generating manpages, delete outdated targets
first., 2007-08-02) and f9286765b2 (Documentation/Makefile: remove
cmd-list.made before redirecting to it., 2007-08-06) created these rm
instances for a very rare corner-case: building as root by mistake.

It's odd to have workarounds here, but nowhere else in the Makefile--
which already fails in this stuation, starting from
Documentation/technical/.

We gain nothing but complexity, so let's remove them.

This is curious.  I understand what other kinds of trailers like
Helped-by and Suggested-by people sometimes use mean, but this one
does not tell anything other than that this person had some comments
on an earlier rounds, does not tell us what kind of comments they
were and if something was done to address those comments or the
comments were totally ignored or what.

The patch text itself, and the justification given in the second
paragraph, both make perfect sense to me.
