I'm not sure that Pavel's idea is the right way to attack the problem,
but I don't agree with this either. Line numbers are really the only
feasible way of identifying a position in a large function. I usually
bring up the function source code in vi and then use j with a repeat
count to find the offending line. It's not uncommon for me to have
various places in the function that look somewhat similar, so
expecting me to find the right place other than by the line number
would not work very well for me.
