Hm...  Well, it might be more user-friendly, but I think it would be
slightly surprising to also change the -fg colour when you set -bg on
the command line.  The foreground colour may be specified in .Xdefaults
or something.

I guess if there is absolutely no foreground colour specification, then
setting the foreground upon -bg black would be friendlier, but what if
the user said -bf "#000001" (i.e., "almost black")?

So I think special-casing one particular value to DWIM would be
difficult to justify, and I'm closing this bug report.
