This is all such an unreliable mess.  Perhaps our file name recorder
should never forget any file and just record the name and the purported
nesting.  And when an error occurs, it checks every recorded file name
in some intelligent order, preferring loaded files over non-loaded ones
and ignoring non-existent pseudo-files, and then using the first match
for the error context lines.

Or tell people to configure file-line error messages.
