I would like to retract this baseless assertion! Reading the subversion
docs ("Externals Definitions") indicates that "svn up" does notice and
recursively update a changed svn:externals definition. Furthermore, I
have confirmed this behaviour in practice using a test repo.
The probably reason I was seeing no apparent update of the externals
with "svn up" was that the old and new contents were identical, having
not deviated since the branch, and svn is clever enough to notice this
and detect that there is nothing to do. Cleverer than me, apparently.
Kind regards,
