in Imake.rules: * Allow XCOMM to be preceded by whitespace and provide a means of generating * output lines with trailing backslashes. * Allow XHASH to always be substituted, even in cases where XCOMM isn't. In particular, this fixes an issue pointed out by wiz on tech-x11, where "@@" remains unsubstituted for "\" in "startx".
