An interesting option (heh!) would be to implement what argp does, which
is to allow users to write a prefix of the long option if it’s
unambiguous:

Apart from that, the conventions we follow are indeed those:

  https://www.gnu.org/prep/standards/html_node/Command_002dLine-Interfaces.html

though the parser we use, (srfi srfi-37), has small differences.
