Thanks. The macro basically works. But when I said "perceive a change of indent as a paragraph boundary", what I meant was that if one set of lines is indented to a different depth from other lines that are adjacent to it, that the macro would see these as being two distinct paragraphs.

Maybe that's not necessary. In fact, I probably don't need it. So I'll probably just use your macro as it is, but without the last line.

Sorry I asked the question and then forgot for so long to check back for the answers...

Anyway, the object I had in mind was to combine that with a macro of my own for reflowing text in a selection. Put them together, and you get something to reflow the paragraph the cursor is in.

Here is my reflow-selection macro:



The neat thing about this macro as it stands now is that if you select multiple paragraphs, it preserves the spaces between then and reflows each one individually.
