It would be nice if there is a way I can provide completion-at-point
with two tables and it will just try them one after another if the
preceding table has no match.

In most cases path starts with no leading / and function completion
needs to work well in strings too due to its inline functions:

   f = inline("sin(x)^2 + 2");

Octave's syntax is eccentric.

A 80% solution might be to special-case 'cd', 'rmdir', 'source',
'unlink' etc.
