Further discussion on IRC with Jonathan and George suggests the

- Deprecate the whole current gnome-exec.h API.

- Add the following functions non-deprecated to gnome-exec.h; they
work with g_spawn-style NULL-terminated argv vectors and should allow
the whole range of current gnome-exec functionality with g_spawn.

char **gnome_prepend_terminal_to_argv         (char **argv); 
char **gnome_commandline_to_shell_argv        (char  *commandline);
char **gnome_commandline_to_terminal_argv     (char  *commandline);
char  *gnome_argv_to_shell_quoted_commandline (char **argv);
