Subject: Bug in insline() and patch


insline (source in libsrc/pc/src/gppconoi.c) does not work correctly.
The bug can be seen by writing a screen full (i.e. with cputs), use a goto(1,1)
then insline() and writing again one line. This sequence should scroll
a text one line up (and it does so with Borland C).
The following patch also deletes a not used variable.
