This came up a few weeks back, but I quickly lost the conversation.
Shouldn't the quotation environment work as it does in LaTeX? If one
has a \startquotation after a paragraph break (white space, or \par)
and a break after the \stopquotation, then the following paragraph
should understood to be new, and hence requiring a first line indent.
If, however, there are no breaks, then the quote is understood to be a
part of the larger paragraph on either side of it, and hence the text
after block quote is not indented. (And might this be default
behavior? Relevant, say, if typesetting a DocBook doc with its
blockquote element.)
Seems to me this is easier and more elegant than specifying some option
every time one wants to use the command...
