Maven bash-completion entry on Gentoo

Put the simple file in "/usr/share/bash-completion" with the ones I use most.

#!/bin/bash

_m2_make_goals()
{
  plugin=$1
  mojos=$2
  for mojo in $mojos
  do
    export goals="$goals $plugin:$mojo"
  done
}

_m2_complete()
{
  local cur goals

  COMPREPLY=()
  cur=${COMP_WORDS[COMP_CWORD]}
  goals='clean compile test install package deploy site'
  goals=$goals _m2_make_goals "eclipse" "eclipse"
  goals=$goals _m2_make_goals "eclipse" "clean"
  goals=$goals _m2_make_goals "dependency" "tree"
  goals=$goals _m2_make_goals "dependency" "list"
  cur=`echo $cur | sed 's/\\\\//g'`
  COMPREPLY=($(compgen -W "${goals}" ${cur} | sed 's/\\\\//g') )
}

complete -F _m2_complete -o filenames mvn

And then the "eselect bashcomp enable "
Will be overwritten the next time the gentoo ebuild for bashcomp is updated or reinstalled.
