Re: restraining @center location and add other centering environments?

[Karl Berry]

    @address@hidden Centered and in code text}

It's erroneous, since @center has to start at the beginning of a line.

    @center A centered address@hidden is 
    a footnote for centered text} with a footnote

It's erroneous, since the newline after "This is" is the end of
@center's argument.

    What I propose is that @center should only be used in toplevel text

It depends on what you mean by top-level.  The canonical use of @center
is within @titlepage.  It can't be used as (part of) an argument to
another @-command, for sure.
    
    and that any @-command opened in @center should be closed before the
    end of line.

Yes.

    To still be able to center some text flexibly I think that a new
    environment similar with @flushleft and @flushright (maybe called
    @flushcenter?) should be introduced.

Oleg already defined @raggedcenter, in fact (I asked him to remove the
doc though since a use for it was not apparent), and @flushcenter would
not be hard either.  (Filled vs. non-filled text.)

I don't have a problem with either of these, but I'm not anxious to
define new commands that no one has ever requested, either ...
maybe after the texi2html switch.

    Also a bracketed environment could be introduced, to be used in paragraphs
    or in @item or in titles or other in-text environments. Like, for example
    @centeredtext{Some text centered}

It couldn't be feasibly implemented in TeX, in general.  It would have
to close the paragraph, do the centered text, and start a new
paragraph.  And that can already be done with @center.
