Is it an accepable style

["Sergey I. Panov" <sipan mit edu>]

It is not clear to me what is an acceptable stile and what is a bad
one.

I have not seen ?: expressions used in the code. Whould that qualify 
as an acceptable style:
        ...

	/* Don't use gettext on the empty string since gettext will map
	 * the empty string to the header at the beginning of the .pot file.
         * And subtree stock items should be restricted to dgettext  */

	label = create_label ( uiinfo->label [0] == '\0'?
			       "":(type == GNOME_APP_UI_SUBTREE_STOCK ?
				   D_(uiinfo->label):L_(uiinfo->label)),
			       &keyval);
         ...
