Yes, this is expected. Nothing specific to the particular function you
are calling. See

  
http://www.gnu.org/software/octave/doc/interpreter/Octave-Sources-_0028m_002dfiles_0029.html

The parser interprets space inside of [] or {} as separating elements of
the matrix or cell array, so canonicalize_file_name is called with no
arguments. For these kinds of uses, you have to remove the space after
the function name.
