[dwm] draw.c[80]: if((dc.w = dc.x - x) > bh)

[Karl.]

I'm looking at the status-text drawing functions and thinking about 
attempting some patching, to scratch one of my itches.

At line 80 of draw.c (hg tip), I find this line:

        if((dc.w = dc.x - x) > bh) {

As far as I can see, it is comparing a width with the bar height.  Does 
this make any sense?  Am I grossly misunderstanding?

thanks,
Karl.
