I don't think that worked before either, Jim...
This is an old problem, with two parts to it.
#1: "more" cannot go back on stdin, try "more < file" and
you'll see.
#2: "more" will process stdin after any command-line arguments
Item #2 had untoward consequences if the pager got invoked via "R <
something". "more" would eat the rest of the input to R (except
for
the bits that were already buffered, so you'd only see it on large
source files)! So the pager was setup to do "more < file". In
particular, it broke "make tests".
What I normally do is to run R in an xterm with a scrollbar and use
that to go back. Alternatively, you can set PAGER=less, which *can* go
back on stdin but has this annoying screen-switch effect where the
information disappears just as you want to use it... Or you can dump
the "<" from $RHOME/cmd/pager, and suffer the consequences.
