I think just output it as −, or as the numeric entity or raw
UTF-8 character depending on settings.
I guess it was not output as − because this was not an entity in
older versions of HTML, or it wasn't supported by browsers or the minus
sign didn't exist as a distinct codepoint in 8-bit encodings, but if
the user puts @minus{} in a document (which is rare), − is a fair
translation of this.
I think it is the %xml_text_entity_no_arg_commands_formatting hash in
tp/Texinfo/Convert/Converter.pm that needs to altered.
