A few questions:
- What is a line of code?
while ( condition_a and condition_b and condition_c)
are both lines, but the first one has three potential bug and the second
ond two. Are these tools that you use able to take that into account? Or
maybe some preprocessing needs to be done:
while ( condition_a and
which makes it three lines. Also, what happens with lines that only hold an
'end' or so?

beware: executing code is not testing behaviour; i guess that the recently
uncovered leaders (repaired by don) is executed in the tests but it was
still there; actually it was uncovered when dvi output from tex (texbook)
was compared to dvi output from nts (it had to do with some rounding; the
texbook also had the bug but it was kind of maskered).
