This came up in the context of Docker, but it seems it wasn't possible for hledger-web to serve remote clients directly (without a proxy) because of 127.0.0.1 being hardcoded ? Now that can be changed with --host=IPADDR. The default base url also uses this address, rather than "localhost" being hardcoded. Also, the --server flag sounded too close in meaning to --host so I've renamed it to --serve. The old spelling is still accepted, at least through the next major release I suppose.
