commit b3d566f570f4416299240b51654b70c74f6cba6a
Author: Martin Liska <mliska@suse.cz>

    Update merge.sh to reflect usage of git.
    
    After switching to GIT, we should use it in libsanitizer
    merge script. I'll do merge from master as soon as
    PR95311 gets fixed.
    
    I'm going to install the patch.
    
    libsanitizer/ChangeLog:
    
            * LOCAL_PATCHES: Use git hash instead of SVN id.
            * merge.sh: Use git instead of VCS.  Update paths
            relative to upstream git repository.
