[PATCH 0/2] Teach 'git grep' about --open-files-in-pager=[<pager>]

This supports opening the results of a 'git grep' directly in a pager (where the pager can be 'vi', too).

This series is purely about convenience, everything the option does can be done with a regular script or command line.

But I saw so many people doing their own scripts for that, and in many cases, they are subtly broken (e.g.

	git grep -z <expr> | xargs -0r vi +/<expr>

would work as long as you do not have to check the exit status of git grep from another script) that I finally decided to go for it and send this patch pair.

My most common use case for this is to do something like

	git grep -Ovi SomeJustRenamedFile

to edit all files I might have forgotten to change after a git mv.

(Actually, to be honest, my use case involves -Pvi, but I will have to retrain my hands.)

  grep: Add the option '--open-files-in-pager'
  grep -P: allow optional argument specifying the pager (or editor)
