    Allow ChangeLog entries for ignored location.
    
    We should be able to generate ChangeLog entries for
    commits like b3d566f570f4416299240b51654b70c74f6cba6a.
    I'm going to install the patch.
    
    contrib/ChangeLog:
    
            * gcc-changelog/git_commit.py: Parse changelog entries for
            ignored locations.
            * gcc-changelog/test_email.py: Add new test for it.
            * gcc-changelog/test_patches.txt: Likewise.

+Subject: [PATCH] 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.
