checkout from neighbour branch undeletes a path?

[Peter Vereshagin <peter@vereshagin.org>]

Hello.

Am wondering if 'checkout branch path' undeletes the files? For the example
below I'd like the 'file00.txt' to be deleted and never checked out from the
previous branch... How can I do that?

  $ git init                                                                                             
  Initialized empty Git repository in /tmp/repo00/.git/
  $ mkdir pathdir
  $ echo test00 > pathdir/file00.txt
  $ git add pathdir
  $ git commit -am 'added file00.txt'
  [master (root-commit) d4f7c70] added file00.txt
   1 files changed, 1 insertions(+), 0 deletions(-)
   create mode 100644 pathdir/file00.txt
  $ git branch -m master branch00
  $ git branch branch01
  $ rm pathdir/file00.txt
  $ echo test01 > pathdir/file01.txt
  $ git add pathdir
  $ git status
  $ git commit -am 'added file01.txt; removed file00.txt'
  [branch00 c3e78ff] added file01.txt; removed file00.txt
   2 files changed, 1 insertions(+), 1 deletions(-)
   delete mode 100644 pathdir/file00.txt
   create mode 100644 pathdir/file01.txt
  $ git checkout branch01
  Switched to branch 'branch01'
  $ rm -r pathdir
  $ git checkout branch00 pathdir
  $ find pathdir/
  pathdir/
  pathdir/file00.txt
  pathdir/file01.txt
  $

I know about 'merge' and it's not the what I need:  to import only the
particular subdirectory from the previous branch.

Thank you.
