Can not 'git add file'

Hi.

How to reproduce

$ git-number
On branch master
Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git checkout -- <file>..." to discard changes in working directory)

1 modified: ../lib/Devel/DebugHooks.pm 2 modified: ../lib/Devel/KillPrint.pm 3 modified: 00-simple.t

Untracked files:
  (use "git add <file>..." to include in what will be committed)

4 ../lib/Devel/DebugHooks/ 5 ../lib/Devel/ImportArgs.pm 6 ../lib/Devel/KillPrintTest.pm 7 ../lib/Devel/KillPrint_scope.pm 8 ../lib/Devel/PkgAtCompileTime.pm 9 ../lib/Devel/t.pl 10 lib/Devel/AutoInit.pm 11 lib/Devel/DZVii.pm

no changes added to commit (use "git add" and/or "git commit -a") $ git add -p ../lib/Devel/DebugHooks/Commands.pm No changes.

I want to start track file here, but I do not want to stage while file.

It seems the git can not process this case and do not allow me to complete that.
