Replace mapcar with mapc because accumulation of the results was not
needed. (git-blame-cleanup)

Replace two occurrences of (save-excursion (set-buffer buf) ...)
with (with-current-buffer buf ...). (git-blame-filter and
git-blame-create-overlay)

Replace goto-line with (goto-char (point-min)) (forward-line (1-
start-line)). According to the documentation of goto-line it should
not be called from elisp code. (git-blame-create-overlay)
