Thank you Stephen.
Yes, in the mean time I have confirmed that this is only in julia
versions 0.3... i.e. all developer versions since about February when
they release 0.2.1 --- After the several hours of compilation from the
source I confirm that indeed,  julia 0.2.1 still contains julia-basic
and julia-readline  plus a symbolic link
  julia ->  julia-readline

Well, "ok" yes, but failing TAB completion even in emacs24 (the
completion happens with programs known to the *shell*)... but I think
that's expected.

Note that  Emacs 24 + *julia*  (M-x julia)  work fine together.
It is just  Emacs23 + *julia* that has the problematic behavior....
but that will affect many many users of Linux versions that are
decendents of debian, notably Ubuntu, Mint, ...
