Now, they aren't, since this discussion is about a possible
svn_cmdline_rintf/svn_cmdline_fprintf. But if we can say that we "only"
suport system where the execution character set for narrow characters (char)
is based on ASCII, this problem should go away because apr_psprintf only
outputs ASCII characters when formatting numbers. Is there anyone who thinks
this is a limitation? Else we could just drop the discussion and go on with
more interesting things:-) Else, we have other problems in the svn code I'm
afraid. For example, when looking at internal paths, we check for the slash
character by the character constant '/' (in the execution charset). If this
doesn't match UTF-8/ASCII, then we're in trouble and have to use constants
for the code point instead.
