[Ctags-devel] [PATCH] Add support for installing readtags command with --with-readcmd

[Maxime C. <fr...@gm...>]

Hello,

Here is a patch that enable installing the readtags command along with
ctags. readtags is already useful as is, and provides a nice shell
based way of retrieving information from the tags file, so it makes
sense to provide a way to install it.

More specifically, Kakoune (my code editor) ctags support relies
on the readtags binary being available, so I'd like to make its
installation as easy as possible.

Cheers,

Maxime Coste.
