This matches the behaviour of both GNU dc (as specified in
its man page), and BSD dc (where stack_popstring() pops
only if the head is a string.)
Add a couple of tests to verify this behavior.

To run the test suite, change to this directory and run "./runtest". It will
run all of the test cases, and list those with unexpected outcomes. Adding the
-v option will cause it to show expected outcomes as well. To only run the test
cases for particular applets:
./runtest <applet1> <applet2>...
Set SKIP_KNOWN_BUGS environment variable to any non-empty value
to exclude tests which are known to fail.
Set SKIP_INTERNET_TESTS to exclude tests which require working
internet connection.
Common causes of false positives:
For busybox built against uclibc, /etc/TZ does not exist or does not match
host system timezone setting. For glibc based host systems, timezone settings
are in /etc/localtime.
LANG and LC_xxx environment variables set to non-C locale.
Developer's notes:
The test cases for an applet reside in the subdirectory of the applet name.
The name of the test case should be the assertion that is tested.
The test case should be a shell fragment that returns successfully
if the test case passes, and unsuccessfully otherwise.
If the test case relies on a certain feature, it should include the string
"FEATURE: " followed by the name of the feature in a comment. If it is always
expected to fail, it should include the string "XFAIL" in a comment.
