If the file name is properly decoded (i.e. in its multibyte form), there
can't be a 0x5c byte other than at the beginning of a char.

So this bug can only happens if you pass a unibyte filename.  IOW the
bug is probably in the caller rather than in the file-attributes function.

Please show us the actual situation where this happens, since file names
are normally always multibyte.
