I found that git-log doesn't print characters in --pretty option as follows.

  % git log --pretty=format:'[%x00]%w(0,0,1)' |od -c
  0000000   [  \n   [  \n   [  \n   [  \n   [  \n   [  \n   [  \n   [  \n
  *
  0022320   [  \n   [  \n   [  \n   [
  0022327

I think NUL and "]" should be printed.

Note that git log works as I expected if I use %w(0,0,0) instead of %w(0,0,1), I don't use %w(0,0,1) or I use %x01 instead of %x00.

  % git log --pretty=format:'[%x00]%w(0,0,0)' |od -c
  0000000   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]  \n
  *
  0044640   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]
  0044657
  % git log --pretty=format:'[%x00]' |od -c
  0000000   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]  \n
  *
  0044640   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]  \n   [  \0   ]
  0044657
  % git log --pretty=format:'[%x01]%w(0,0,1)' |od -c
  0000000   [ 001   ]  \n   [ 001   ]  \n   [ 001   ]  \n   [ 001   ]  \n
  *
  0044640   [ 001   ]  \n   [ 001   ]  \n   [ 001   ]  \n   [ 001   ]

I used git 1.7.8.2.

  % git --version
  git version 1.7.8.2
