44 | <para>Reinstalling Readline will cause the old libraries to be moved to

47 | avoided by issuing the following two seds:</para>

52 | <para>Readline contains a bug in its handling of non-multibyte characters,

53 | which can lead to incorrect display calculations and incorrect redisplay.

54 | Fix this issue by applying the following patch from the upstream maintainer:
