[PATCH 2/2] git-svn: fix svn fetch erroneously recreating empty dir placeholder deleted earlier

[Ilya Basin]

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
    )
