svn_uri_canonicalize allows any characters in hostname, A-Z is converted
to a-z, other characters are simply copied:
/* Found a hostname, convert to lowercase and copy to dst. */
if (*src == '[')
while (*src && (*src != '/') && (*src != ':'))
*(dst++) = canonicalize_to_lower((*src++));
What is the canonical form of this?
Should we drop '.' to give:
or do we have to retain it as
and change svn_uri_is_canonical to allow a hostname '.'?
