We do the same thing with the gzip utility for performance. This reduces the runtime of `./bin/base64 enwik8 >/dev/null` from 0.428s to 0.303s. This reduces the runtime of `./bin/base64 -d enwik8.base64 >/dev/null` from 0.632s to 0.469s. (enwik8 is a 100MB test file from http://mattmahoney.net/dc/enwik8.zip)
