>Description:
When there are deeply nested bmake:s and error occurs, for each level nearly 
identical error message is shown which occupies too much space.
>How-To-Repeat:
Run deeply nested bmake:s, e.g. as used sometimes by pkgsrc.
>Fix:
Ideally, I think only the first error should be shown and rest of wasted lines 
just to be skipped. I know that these are independent bmake:s and playing with 
exit codes may not be enough but this is too annoying when it happens.
