Err, we should define how it behaves, not what is inside
it. As long as one can pipe things to $PAGER or use $PAGER on a file,
what it contains should not matter.
The safe bet would be for $PAGER to be a script or executable
which can handle reading from file or STDIN, like proper UNIX
programs.
To make life easier for people writing programs which deal
with $PAGER, and are using the POSIX exce* set of calls, one may
constrain $PAGER to "path [arg [arg ..]]", with no pipes or other
shell meta-characters.
