Updating to readline 7.0 (alpha) causes a lot of testsuite regressions
on a number of (non-x86) platforms.  It may be safer to first upgrade
to readline 6.3 but in that case there are some local patches that
have to be preserved.  So it raises the question of how the ChangeLog
should reflect that some local patches are preserved across the
upgrade, while other local patches are dropped since they've been
applied upstream.  The idea is to make it easy to tell which local
patches are currently applied against our upstream copy of readline
especially across upgrades.
