[ELPA Syncer]

branch: externals/vc-got
commit e9a5df0576d660dfc5d1d3e6bbb45406654e7dde

    make vc-annotate-show-diff-revision-at-line works
    
    Improving vc-got-diff so the diff-at-line works in *Annotate* buffer.
    
    vc-got-diff is still not 100% compliant to the interface thought.  The
    ``diff against an empty tree'' is still missing.
