Good to know, thanks. BTW, have you had a look at the patches I
submitted to the list around 10pm yesterday? What do you think of
them?

Yes it is, and it conceptually belongs to the previous paragraph,
but the following text is not part of the same paragraph and
should therefore start with indentation.

Anything that gives a "paragraph end" should work. This is why in
the patches I submitted I made a small change: it suffices to give
a \noindent, regardless of what comes after, so that:
(1) if paragraph doesn't end (by any mean: no \par, no empty line,
no </para>), the next text will typographically belong to the same
paragraph (i.e. will not be indented)
(2) if paragraph ends (by any mean: \par, empty line, </para>),
the next text will be indented, since the paragraph end will
"absorb" the \noindent.
