recurse_submodules vs recurse-submodules

[Chris Packham <judge.packham@gmail.com>]

Hi,

Just noticed this in git 1.7.4

  git clone -h
  ...
      --recursive           initialize submodules in the clone
      --recurse_submodules  initialize submodules in the clone

  git fetch -h
  ...
     --recurse-submodules  control recursive fetching of submodules

The recurse_submodules option for git clone was added in ccdd3da6 I'm
guessing it wasn't Jens' intention to use an underscore instead of a
hypen. Also as it is fairly new it should be safe to correct without
worrying about retaining the incorrect option for backwards
compatibility.


Here's my attempt at a fix

Subject: [PATCH] clone: fixup recurse_submodules option

The recurse_submodules option was added in ccdd3da6 to bring 'git clone'
into line with 'git fetch' and future commands. The correct option should
have been "recurse-submodules".
