fileparts / fullfile inconsistency

[Francesco Potorti`]

This is what I observe, and I think it is inconsistent.  I do not know
if this is incostintent as Matlab is, though.

In the 1st, 2nd and 4th cases, I can use fullfile to reconstruct what
fileparts has separated.  Not in the 3rd case, though.
This is Octave 3.0.1.

I can propose a changeset if I am told what to do.

octave> [a b c]=fileparts("/dir/file.ext"), fullfile(a,[b c])
a = /dir
b = file
c = .ext
ans = /dir/file.ext

octave> [a b c]=fileparts("dir/file.ext"), fullfile(a,[b c])
a = dir
b = file
c = .ext
ans = dir/file.ext

octave> [a b c]=fileparts("/file.ext"), fullfile(a,[b c])
a = 
b = file
c = .ext
ans = file.ext

octave> [a b c]=fileparts("file.ext"), fullfile(a,[b c])
a = 
b = file
c = .ext
ans = file.ext
