Re: address@hidden: completion of coding systems]

[Richard Stallman]

    +   int count = SPECPDL_INDEX ();
    + 
        if (SYMBOLP (default_coding_system))
          default_coding_system = SYMBOL_NAME (default_coding_system);
    +   specbind (intern ("completion-ignore-case"), Qt);
        val = Fcompleting_read (prompt, Vcoding_system_alist, Qnil,
                              Qt, Qnil, Qcoding_system_history,
                              default_coding_system, Qnil);
    +   unbind_to (count, Qnil);

That would work, but it would be cleaner to use 

    specbind (Qcompletion_ignore_case, Qt);

instead of interning it again.
