I've updated the patch:
- a check that the first character of the path is in [a..z][A..Z] in
is_canonical and svn_path_is_root.
- return type of svn_path_is_root changed from int to svn_boolean_t.

Both patches are added (the 'wc is switched' patch isn't changed).

I'll send a patch for this to the list tomorrow.

Thanks for the review,

Fix an issue where the status of a working copy on the root of a drive is
