options and literal values so that groff does not try to convert them to
hyphens, thus breaking the ability to copy them directly from the manpage
to the command line.
Bump PORTREVISION.
- add a couple of "just in case" string routine fixes - use of snprintf() or
strncpy() where appropriate;
- add some more sscanf() result code checking where needed;
- fix the build when XTEST is not selected;
- change all references to /usr/dict/words to /usr/share/dict/words instead;
- fix a small error in the text of an error message.
