Vim: joining lines having continuation markers

This handy file-renaming script at Perl Monks has source code with red “+” marks marking wrapped lines. I pasted it into Vim and wanted to wrap those lines back to the way they should be. After a bit of fiddling, I got:

:g/^+/execute "norm 0x" | .-1,.j!

The `g/^+/’ finds the lines beginning with a “+”. Then the `execute “norm 0x”‘ deletes the “+” (“0” moves to beginning of line; “x” deletes), “|” marks the next command, and `.-1,.j!’ joins (“j”) the current line (“.”) with the previous line (“.-1”) without whitespace (“!”) added between the lines.

I leave it to you whether I have too much time on my hands.
