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=E2=80=99s
unambiguous:

  https://www.gnu.org/software/libc/manual/html_node/Argp.html

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.
