It's probably the result of drift between the original patch and what
was eventually committed. IIRC, Pavel had it as an environment
variable originally, but Tom and I didn't feel the feature was
important enough to merit that treatment.

That's an intriguing possibility. But part of the point of the
original feature was to be able to say:
\ef somefunc 10
...and end up on line 10 of somefunc, perhaps in response to an error
message complaining about that line. I don't think your proposal
would address that.
