Thanks very much - that works perfectly. Now I must try to understand
_how_ it works!
It breaks down as
:g/pattern1/action
where pattern1 is "find the beginning of a paragraph" and action
is "<range>j" to join a range. The range happens to be "from
this currently-matching line through the last line in the
paragraph". If you have truly blank lines (no whitespace on
them) and blank lines at the top and bottom, you could simplify
it to something like
:g/\n\@<=\n/,/\n\n/j
instead of messing with the "\%$" and "\%^" (end/start-of-file)
and attempting to ignore empty-ish (whitespace-only) lines.
