This version makes dc exit after processing all commands passed via -e or -f
instead of waiting for more input on STDIN (add "-f -" to the command line
to emulate the behavior of versionm 3.1.3 and earlier, if desired).
The version and copyright message are no longer printed for interactive
sessions as was the case with the prior implementation in the FreeBSD base
system.

This release fixes a regression from traditional bc behavior in FreeBSD
with regard to "-e quit" being passed on the command line and add Spanish
message catalogs.
These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:
- They do not depend on external large number functions (i.e. no dependency
on OpenSSL or any other large number library)
- They implements all features found in GNU bc/dc (with the exception of
the forking of sub-processes, which the author of this version considers
as a security issue).
- They are significantly faster than the current code in base (more than
2 orders of magnitude in some of my tests, e.g. for 12345^100000).
- They should be fully compatible with all features and the behavior of the
current implementations in FreeBSD (not formally verified).
- They support POSIX message catalogs and come with localized messages in
Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
and Russian.
- They offer very detailed man-pages that provide far more information than
the current ones.
