This is not an eTeX feature, but a web2c feature.

Yes and no:

tetex 2.x already had the -file-line-error option, but it left out the
error context lines.  That renders the output unusable for
preview-latex, since the error context lines are necessary for
determining the error column.  Newer web2c versions seem to add the
error context lines again.

Could you try finding out which web2c version made the change of
behavior?  When we add this functionality, it would be nice if we
could mention in the docs for which versions of TeX -file-line-error
leads to usable results.
