! #ifndef WIN32
! puts(_("Use control-D to quit."));
! #else
! puts(_("Use control-C to quit."));
! #endif

But Control-C exiting on Windows is a bug, isn't it?
Shouldn't we try to fix it to behave like in Unix
rather than documenting it?

Also, the fact that Control-D can quit in the middle of a
multiline query without any confirmation is a usability problem, because
you can always fat-finger a Ctrl+key. By comparison, bash doesn't
accept it and emits the same error as if a script was improperly
terminated. Example:

$ cat '
> [Hit Ctrl+D here] bash: unexpected EOF while looking for matching `''
bash: syntax error: unexpected end of file
$

There's also the issue that, in general, communicating different hints
and advice depending on the host operating system is not ideal.
Because people ask "how do I do such and such in psql?",
they do not ask "how do I do such and such in psql in Windows?".
