Ah, yes, I forgot about the multiple meanings of this flag in the different
layers. So I agree, both switch and update should carry the
server-recognized meaning of 'ignore-ancestry' in both the client and RA
layers. (Sorry for the mental lapse.)

This may be a bit of a sidebar, but: Does svn_ra_do_status() need the same
treatment? I mean, to the degree that 'svn status -u' is supposed to be a
particularly shaped type of dry-run update, does it also need support for
the --ignore-ancestry flag?
