I've been running my unit tests from a makefile, which triggers
the output to be a compilation buffer which does jump to lines.

The only wrinkle is that Test::Unit inserts leading whitespace
into the line numbers. My hackish solution was to pipe the
standard error through a filter to remove leading whitespace.

## makefile
RBTE= ruby -e "while( (line=gets())!=nil); puts line.strip; end"

test :
	ruby -w tc_unittest.rb 2>&1 | $(RBTE)
## end of makefile


It doesn't trap all lines, but I've been meaning to make it a full blown filter
which recognizes some of occasional backtraces which have lines starting
with: 
from file.rb:line:
