New Revision: 363807
URL: https://svnweb.freebsd.org/changeset/base/363807
Log:
Import version 3.1.4
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.

# News
+## 3.1.4
+
+This is a production release that fixes one bug, changes two behaviors, and
+removes one environment variable.
+
+The bug is like the one in the last release except it applies if files are being
+executed. I also made the fix more general.
+
+The behavior that was changed is that `bc` now exits when given `-e`, `-f`,
+`--expression` or `--file`. However, if the last one of those is `-f-` (using
+`stdin` as the file), `bc` does not exit. If `-f-` exists and is not the last of
+the `-e` and `-f` options (and equivalents), `bc` gives a fatal error and exits.
+
+Next, I removed the `BC_EXPR_EXIT` and `DC_EXPR_EXIT` environment variables
+since their use is not needed with the behavior change.
+
+Finally, I made it so `bc` does not print the header, though the `-q` and
+`--quiet` options were kept for compatibility with GNU `bc`.
+
