version-etc tweak

[Eric Blake]

Back in January, we had a discussion about formatting of --help output.  The 
result was that coreutils changed to a new style.  It has now been several 
months and several releases, with no complaints about the new style.  Also, 
autoconf 2.64 has been released in the meantime, with support for a more 
reliable package URL (if your PACKAGE_NAME starts with "GNU ", then autoconf 
2.64 gives you the same URL as this code gives when using autoconf 2.63, 
without you having to do anything in your configure.ac).  So how about letting 
all other gnulib clients of version-etc pick up this change?

A couple of points to think about.  Right now, standards.texi recommends:

Report bugs to: address@hidden

while coreutils uses:

Report PROGNAME bugs to address@hidden

Depending on what others think, we could easily add a ':' to coreutils, as well 
as modify this patch to reuse last_component(program_name) (which is derived 
from argv[0]).  Also, coreutils renamed its function from 
emit_bug_reporting_address to emit_ancillary_info.

Subject: [PATCH] version-etc: match coreutils style

Coreutils switched to this style on 2009-02-01, with no complaints.
This assumes that PACKAGE_BUGREPORTS and PACKAGE_PACKAGER_BUG_REPORTS
are generally email addresses, not URLs.

* lib/version-etc.c (emit_bug_reporting_address): Drop periods,
and use <> only for URLs.
