patch, 2 partsgit-svn: fix svn fetch erroneously recreating empty dir placeholder deleted earlier

The Fetcher accumulates deleted paths in an array and doesn't reset the array on next commit. This causes different results when interrupting and resuming the fetch. When --preserve-empty-dirs flag is used, a path in the array can be erroneously treated as just deleted, although it was deleted in the previous commit and cause the creation of an empty dir placeholder.

Test script:

    (
    set -e

    rm -rf testrepo.svn testrepo.gitsvn
    svnadmin create testrepo.svn
    url=file://`pwd`/testrepo.svn

    rm -rf testrepo
    svn co "$url" testrepo
    cd testrepo

    mkdir -p foo/bar
    echo aaa > foo/bar/fil.txt
    svn add foo
    svn commit -mx

    svn rm -mx "$url/foo/bar/fil.txt"
    svn rm -mx "$url/foo/bar"

    echo aaa > fil.txt
    svn add fil.txt
    svn commit -mx

    cd ..

    rm -rf testrepo.gitsvn && git svn clone --preserve-empty-dirs "$url" testrepo.gitsvn

    if [ -e testrepo.gitsvn/foo/bar/.gitignore ]; then
      echo "error: testrepo.gitsvn/foo/bar/.gitignore exists"
      false
    fi
    )
