Index: cmd/more.c Fix
Description:
The "more" command calls "stty" even when output is redirected.
It also leaves terminals such as VT100s in "underscore mode"
if the last printing character output is underscored.
Repeat-By:
To reproduce the first bug, present these commands to "csh":
stty tostop
more /etc/passwd > /dev/null &
and note the
+ Stopped (tty output)
message.
To reproduce the second bug, hop on a VT100, present these commands
to "csh":
awk 'BEGIN { printf "a%c_\n", 8 ; exit }' | more
date
and note that all input and output is being underlined.
Fix:
As usual, the trade secret status of the code involved precludes a
clearer posting. The first conditionally compiled section of code
deals with the first bug; the second with the second. These changes
are for the 4.1bsd version of the program.
