I understand how the above works, but I can't find justification
for it in Vim's help. I'd break it down as follows:

:g Begin "global" command
/^\n\</ Find blank line followed by start of word
+ Go forward one line to start of paragraph
; Set cursor to above-calculated start of range
'} Move to blank line after paragraph
- Go backward one line to end of paragraph
j Join lines in paragraph delimited by the range

But looking at ``:help :g``, I see:

:[range]g[lobal]/{pattern}/[cmd]

The analysis above requires some features of a full-bown "range"
(:help range) instead of just the ``/pattern/`` (:help pattern)
that is permissible according to the help for ``:g``. Am I
missing something here? I can't tell if the documentation for
the global command should be expanded to cover this
functionality beyond a simple pattern, or if the ability to use
range-like features is accidental and not supposed to be part of
the global command.

Thanks,
Michael Henry
