Well, to me the whole thing smacks of:

LOG: there is a problem
LOG: please be aware that we logged a message about a problem

The only real argument for the message:

LOG: configuration file "/home/thom/Development/data/postgresql.conf"
contains errors; unaffected changes were applied

...is that somebody might think that the presence of a single error
caused all the changes to be ignored.  And there's a good reason they
might think that: we used to do it that way.  But on the flip side, if
we emitted a LOG or WARNING message every time the user did something
that works in a way incompatible with previous releases, we'd go
insane.  So I think the argument for just dumping that message
altogether is actually pretty good.

Bikeshedding the wording is, of course, another viable option.  For
that matter, ignoring the problem is a pretty viable option, too.  :-)
