Jakub Jelinek has toldme this:
The radline API uses lots of global variables, which make linking against it to
expensive.  The impact on /bin/bash startup might not be neglectable.
Since bash is executed many times during startup and even when processing a more
complicated shell script, one would have to be very careful about performance
impact before dynamic link against readline.

This convinces me that the potential gain is not worth the price of the
investigation, so I'm undoing my yesterday reopen.

Please note that the original reason for the suggestion was that bash used
termcap back then, which is no longer true; it uses terminfo as all civilized
citizens of todays Fedora world.
