Define "nicely".

For example, many pagers don't work well when stdin is line-buffered (they assume they'll see individual key presses as they happen)

Pagers can also conflict with keys that the terminal emulator is using for a different purpose. This is especially annoying when the terminal emulator is using those keys for pager-like functionality in the first place!

An example of both of these is Emacs `shell-mode`.

(I personally set `PAGER=cat` in my Bash profile, which avoids most of these shenanigans)
