[Tfug] OK, I need one more funky little sed or bash code...

[Jim March]

Folks,

I need to find every line that ends with a "{" character and put a new
line right above it, exactly like this:

      } #

...ONLY so long as that line to be added doesn't already exist!

Follow?  Now, lines that end in "{" vary.  Here's some examples:

      threaten voting equipment={

        gather knowledge={

          from insider={

They're all indented with either six or eight or maybe 10 and even 12
spaces...maybe that'll help, I dunno.

Anybody?

:)

Thanks!

Jim
