Re: [RFC] [PATCH] Use console, not stdin/stderr, for prompting

From: Julian Foad <julian.foad_at_wandisco.com>

Just a reminder about putting this functionality in APR, in case some
people in this thread aren't aware:

When we discover some functionality that would ideally be provided by
APR but isn't, such as this, then we should write it in such a way that
it is suitable for inclusion in APR (except for needing an "apr_" prefix
instead of "svn_"), and then after we've got it into Subversion we can
then propose it to the APR project and there is a good chance that it
will be accepted. Then we make our configury use the APR implementation
if available and our own implementation if an older APR is being used.
A long time later, we stop supporting the older versions of APR and then
delete our implementation.
