Add list of meaningless commits to .git-blame-ignore-revs

Works nicely together with:
    git config --add blame.ignoreRevsFile .git-blame-ignore-revs

The list was generated by hand-picking from git log --oneline augmented
with:
    --author=tbox
    --grep=clang-format
    --grep=copyright
    --grep=reformat
    --grep=whitespace
plus
    git log --format='commit %H %s' --stat | grep -E 'commit|changed' | grep -B1 '[0-9][0-9][0-9] files changed'
plus some sanity checking.

Comments were added with:
    for COMMIT in $(cat .git-blame-ignore-revs)
        do git log -1 --format="# %s" "$COMMIT"
        echo $COMMIT
    done
