It goes wrong in:
> subversion/libsvn_subr/commit.c:1390
> subversion/libsvn_subr/target.c:81 svn_path_condense_targets :

  for (i = 1; i < targets->nelts; ++i)
    {
      const char *rel = APR_ARRAY_IDX(targets, i, const char *);
      const char *absolute;
      SVN_ERR(svn_path_get_absolute(&absolute, rel, pool));
      APR_ARRAY_PUSH(abs_targets, const char *) = absolute;
      *pcommon = svn_path_get_longest_ancestor(*pcommon, absolute, pool);
    }

where *pcommon = "X:/folder1" and absolute is "X:/folder2", the call to
svn_path_get_longest_ancestor will return "X:". This is a) not correct
and b) functions like svn_path_dirname will not correctly identify this
as a root path.

This is a very specific case and can easily be checked for, but in 1.5.x
there's nothing more you can do than abort the commit and return an
error message like "Committing multiple items on the root of a drive is
currently not supported, please commit items individually". Obviously
this is windows-only.
