[PATCHv4] git-log --format: Add %B tag with %B(n) option

Since one can simply use spaces to indent any other --pretty field we should have an option to do that with the body too.

Also the %B flag strips the trailing newlines, to enable more compact display.

Hey,

I moved the indent >= 0 check to the caller. Also changed the documentation, n should indicate more strongly that n is supposed to be a natural number.

You mentioned small style issues but I'm not sure what you meant. One thing that could be made more compact is calling pp_remainder(CMIT_FMT_MEDIUM, &body, sb, indent < 0 ? 0 : indent); and thereby saving two extra lines. I saw this at a lot of other spaces in git.git, but saw no specific guideline in CodingGuidelines.

Yet another option is aborting for negative indent values, issuing return 0;

Greetings, Jojo
