Version 1.5.1
Change command line parsing to allow -F and similar flags without a space between the option and the argument (allowed by POSIX), for example -F: (thanks Arnold Robbins)
Also tweaked output of -version to be just the bare version tag so it's machine-readable. -h or --help now includes the copyright message.
First release with binaries attached (see make_binaries.sh). Thanks @cup.
