Right.
It seems to be coming from /usr/bin/less.
So I tried to suppress by setting the PAGER environment variable to
/bin/cat. No luck.
The code in main.c:setup_environment ought to use the PAGER
environment variable if it is defined. This would require changing
scroll_command field, probably from an int to a string containing the
command's path. (It is probable that a copy of the string need not be
created since environment variable values are stable.) I would be
willing to propose a patch if you (Dave) would be willing to consider
it.
It turns out that the crash command
set scroll off
does what I need. The crash(8) man page did not even hint at this
capability.
