Description

If I have svn:externals with explicit fixed revisions, their commit is usually
blocked because they are "out of date" (i.e. when the explicit revision number
is older than HEAD).

However, if I happen to set the explicit revision number to HEAD, a commit to
the external does a peculiar thing: it commits a new revision to HEAD and, upon
update, restores the preceding fixed revision. This happens both for file- and
directory-externals.

This will rarely happen in practice; but it would be more accurate to guarantee
that externals with a fixed revision are blocked from commit per se.

(It has been said that this will be relatively easy to accomplish once wc-ng has
unfolded.)
