I think the whole point here is that we use only one way to invoke
external programs.  And probably nobody wants to go down the
lane that leads darcs having interfacing code for all sorts of diffrent
programs on diffrent platforms.

Maybe, as a long-term plan, all darcs external programs should be
parametrisable via environment variables (and maybe some file) and
use similar syntax as --sendmail-command.  Then we could have
syntax (or maybe deduct from used variables) whetever standard
filehandles need to be bound to files, null or console.
