 * Compiles lesskey source into the binary a `-k` file carries, like

 *
 * NOT exposed as a command. less ships `lesskey` as a separate program
 * and this pager deliberately does not: an npm install has no business
 * putting a compiler on anyone's PATH, and a source file is the better
 * thing to keep anyway. It exists for --edit-lesskey, which has to
 * write a binary back where it found one.
 *
 * It is a PORT, not a re-invention - the byte layout, the escape
 * handling and the error messages all follow less, and the tests compare
 * its output against the real `lesskey` binary byte for byte.
