Thanks.  It all looks to me as differences in personal preferences.  I
have no doubt that some of us (myself included) have no problems
finding the current line in the source buffer, and others use
hl-line-mode with the above code and have no problems at all.  So I
wonder what would be the best way of adding the feature you want
without disappointing those who like the existing behavior.
