[fd895bf]31<para>The following patch is only necessary if Readline was not
32installed as suggested. This patch fixes a problem where Bash
33sometimes limits 33 characters to a line before wrapping to the next
34line. If Readline has been installed per the instructions, this patch
[5fc710e]35is not necessary because the patch applied to the Readline package
[fd895bf]36already resolves this issue.</para>
