Fixing escape bug for multiple excludes in Git Bash in Windows

Getting an error "is not recognized as an internal or external command" when having multiple excludes in Git Bash in Windows 7. Changing from ' to " will fix the problem in Git Bash.

I have not tested the change in other environments then Git Bash + Windows 7

Before:

    $ svn2git --username hallvard -m --authors ../svnauthors --rootistrunk --metadata -v http://svn/repos/url --exclude 'DirectoryA' --exclude 'DirectoryB'
    Running command: git svn init --prefix=svn/ --username=hallvard --trunk=http://svn/repos/url
    Initialized empty Git repository in c:/git/tmp/merge-test/mainRepo/.git/
    Using higher level of URL: http://svn/repos/url => http://svn/repos/SVNRepo
    Running command: git config --local svn.authorsfile ../svnauthors
    Running command: git svn fetch '--ignore-paths=^(?:)(?:DirectoryA|DirectoryB)'
    'DirectoryB)'' is not recognized as an internal or external command,
    operable program or batch file.
    command failed:
    2>&1 git svn fetch '--ignore-paths=^(?:)(?:DirectoryA|DirectoryB)'



After

    $ svn2git --username hallvard -m --authors ../svnauthors --rootistrunk --metadata -v http://svn/repos/url --exclude 'DirectoryA' --exclude 'DirectoryB'
    Running command: git svn init --prefix=svn/ --username=hallvard --trunk=http://svn/repos/url
    Initialized empty Git repository in c:/git/tmp/merge-test/mainRepo/.git/
    Using higher level of URL: http://svn/repos/url => http://svn/repos/SVNRepo
    Running command: git config --local svn.authorsfile ../svnauthors
