gh-148321: use --quit-if-one-screen option for the pager (new REPL) 
Currently, by passing --clear-screen (-c) to the pager --- small texts (like
few-sentences docstrings) are shown at top of the screen, just as big texts.

I believe it would be better to show this inline instead, not clearing
last session commands with output and so on.  BTW, this is the default
for git commands, e.g. git-log.  Of course, we loose on this way ability
to use pager for search, but terminal emulators usually have similar
capability on its own.
