[tex4ht] [bug #242] Spurious semicolon produced by \textregistered command

[Karl Berry]

    +require "luatexbase.mcb"

By the way, I didn't see this file in the patch (or in TL).
Not that it matters if we go the other route.

    +luatexbase.add_to_callback("open_read_file", patch_latin1, 

1) For what it's worth, luainputenc.lua uses process_input_buffer instead
of open_read_file.  I don't know if performance is better.

2) Isn't the whole issue about Latin 2, not Latin 1?
