Line numbers in stack traces

[Richard A. O'Keefe]

I pointed out that macros make source line numbers much less
useful, lamenting that Erlang has such things.

I just extracted all the non-white-space non-comment non-'end' lines from
the *.[ehy]rl files in an Erlang distribution, and found that

one line in 94 is a -define.

This is a *higher* proportion of -defines in Erlang/OTP than
I have #defines in my C code!
