The Matlab docs mark vectorize as "not recommended" and only state that 
the input can be a character vector, string scalar, or inline function 
object.

Octave's vectorize function has always been bad.  For example, try

  vectorize ("fprintf ('the file is: /foo/bar\n')")

in an old version.

If you think it is worth doing, I could probably restore the old buggy 
behavior for anonymous function handles and character strings.
