Excess spaces in info copyrights; inconsistent @copyright{} usage.

["Andrew M. Scott" <amscott1@sedona.ch.intel.com>]

I noticed two anomalies in the current info/texi files:

1. There are excess spaces in the generated Copyright lines in many
   but not all info files; I'm using makeinfo 4.8. This seems to occur
   for files with more than one line of copyright dates.

2. Some of the *.texi files use the @copyright{} construct in their
   copyright lines (e.g. erc.texi), and some don't (e.g. elisp.texi).

Samples:

A. elisp.info snippet:

   This is edition 2.9 of the GNU Emacs Lisp Reference Manual,
corresponding to Emacs version 22.0.50.

     ^^^

here is the corresponding snippet from elisp.texi:

A quick spot-check showed similar excess spaces in the info files for
eshell, woman, and ebrowse, but *not* pcl-cvs or message.

B. The space in url.info appears to be due to hard spaces in the
   url.texi file.

C. The erc.texi file is an example of a file using the @copyright{}
   construct (in constrast to elisp.texi):

This manual is for ERC version 5.1.2.
