liba2i-1.0-rc4 - string-to-numeric library

Pre-release for packagers to try.  Changes:

-  Reduce what `make && make install` does to the minimum expected by
   packagers.

RELEASE: Push the tag before sending mail

This makes sure that when readers receive the email, they can already
access the tag.

Also, make the second email a FWD of the first, to not need to repeat
that info.
