  If I could avoid defining another set of different macros, I would
prefer... (For I have already 2 start macros, 2 stop macros, and 1
intermediate macro: it already lacks a bit of automatising).

  So, with the [before=] (and [after=] for continuing text after
\stopnarrower), it is possible.

  Here is what I have done so far. Not too bad a result, but there are
still 2 main problems:
-- when the quotation begins after the beginning of the paragraph, the
whole paragraph is affected by *narrower*;
-- when the text continues after the end of the quotation, it is
impossible to insert the *\par* that, as Hans noticed and told us, is
needed to have *narrower* work, so it is as if there was no *narrower*
and the whole line numbering of the paragraph is messed up.

and 2 minor ones:
-- no paragraph indentation in footnotes.
-- Alignment of the first quoted paragraph in respect to the following
quoted paragraphs is not perfect (because I use different symbols for
the quotation opening («) and the quotation repetition (»), I guess).
But this point is good enough for me.

\starttext

First check: «normal spacing of guillemets».

Second check: a normal paragraph, to show {\bf normal right margin limit}.
\input tufte


«Third check : paragraph starting with guillemets.»

Let's start with a quote block on a {\bf new line} :

\startbloccite
%First paragraph ({\bf quote repetition symbol is really not wanted here}): \input tufte (\the\hsize)
Second paragraph ({\bf indenting and margins are correct}): \input tufte
\bloccitepar
Second paragraph ({\bf indenting and margins are correct}): \input tufte
\bloccitepar
Third paragraph ({\bf now I put a different sentence here to check hyphenation.
Weird, it looks OK now, I cannot reproduce the overflow.}): \input tufte
\stopbloccite

Now, a quote block starting just there, {\bf in the middle of a line}
({\bf the problem is that \char`\\startnarrower affects the whole paragraph :
every lines are narrowed, even the ones before the environment starts}):\startbloccitel\input tufte
\bloccitepar
\input tufte
\stopbloccitel . This a bit of text at the end of the quotation.
{\bf The whole paragraph is wrong because I could not end it with a \char`\\par}.

And let's call a {\bf footnote}\footnote{\startbloccite\input tufte
\bloccitepar
\input tufte
\stopbloccite}. {\bf Fine : quote repetition symbols do now appear
in it. But there is no paragraph indentation.}.

\stoptext

Goodbye,
  Stéphane.
