RFC: Readline 5.1 import

[Elena Zannoni]

FWIW when you leave things open ended, and say you are in no hurry and
going to wait, please, before pointing fingers, specify what time
frame you are thinking of. I cannot read your mind.

We do already have a branch named FSF where the readline imports have
been done before. The same branch has ben used for importing pristine
versions of texinfo. It seems the people you have asked must not be
used to track code from 3rd parties, and are willing to cut corners.
Anyway, I have prepared things for you to do the real merge. I have

- imported 5.1 on the fsf branch. 
- Tagged the readline sources 
- created a branch for the merge to happen there.

What you need to do now is check out the branch
readline_5_1-import-branch for gdb+dejagnu

then do 
cvs update -jFSF:yesterday -jFSF src/readline

resolve the conflicts, cvs add new files, cvs rm files (and
directories), and commit. I would suggest letting a few others give it
a spin on the branch with exotic architectures, then merge everything
into mainline in a single swoop.  Note that you need to delete
yourself the files that have disappeared from readline between 4.3 and
5.1 if any, cvs will not do that automatically.
