PVS-Studio warning V528 for TortoiseGIT

static const char *
fuzzy_escape(const char *src, apr_size_t len, apr_pool_t *pool)
{
  const char *src_orig = src;
  ....
  while (src_orig < src_end)
  {
    if (! svn_ctype_isascii(*src_orig) || src_orig == '\0')
  ....
}

Most likely this is what should be written here: if (! svn_ctype_isascii(*src_orig) || *src_orig == '\0').

This suspicious code was found in TortoiseGIT project by PVS-Studio static code analyzer.
Warning message is:
V528 It is odd that pointer to 'char' type is compared with the '\0' value. Probably meant: *src_orig == '\0'. utf.c 501
