[ITCM] bison dash grep gzip m4 readline sed

[Brian Inglis]

Hi folks,

Once again been looking over commonly used outdated packages I use 
frequently which need upgraded and picked another few of Eric Blake's I 
would like to request to co-maintain and upgrade as they are a few years 
old.

Attn: Eric Blake - advice, comments, concurrence or objections to my 
co-maintaining the packages for bison dash grep gzip m4 readline sed?

I am as usual dogfooding these, including rerunning the builds and 
checks after local installs on both arches, but would appreciate any 
advice about whether any or all of these should be test releases (e.g. 
readline) before upgrading stable releases (given some recent issues I 
caused) or other comments or suggestions.

These builds have all been tested in the git-cygwin-package playground 
repo; see:

	https://cygwin.com/cgi-bin2/jobs.cgi?id=3148..3151,3154-3156

commit links show the package and log links show the results.

[I am working up to looking at dealing with bash and/or coreutils: any 
suggestions for less significant packages to tackle for more experience 
upgrading packages needing Cygwin tweaks would be welcome! ;^>]
