Comint and completion

[Andrea Crotti]

One thing I miss from emacs is that whenever I start an interpreter
inside it, I don't get any tab-completion.

For example ghci started inside emacs doesn't complete with TAB, while
in a "normal" shell it works perfectly.

I saw that for example the shell (which instead works correctly) has
bound to tab (comint-dynamic-complete) but it apparently only works with
the shell.

Would it be so hard to have the same behaviour of the tab key in emacs
comint buffers and in the shell?
