[G. Branden Robinson]

Update of bug #45502 (project groff):

                  Status:                    None => Confirmed              
                 Summary: .if, .ie, .el syntax issue => .if, .ie, .el parsing
incompatible with V7 Unix & Heirloom troff

    _______________________________________________________

Follow-up Comment #1:

Confirmed.

Output from V7 Unix nroff and Heirloom Doctools 191015 troff is as Carsten's
example of correct output, with added newlines (maybe Savannah stripped
them)?
