<pre>The following invocation (to be modified depending on load path of
clang-format.el and location of the clang-format binary)
emacs -batch -q -l clang-format -eval '(progn (write-region "int a;\n" nil
"/tmp/clang.cpp") (find-file "/tmp/clang.cpp") (narrow-to-region 2 3)
(clang-format-buffer))'
results in an error
(clang-format failed with code 1: error: offset 1 is outside the file)
because clang-format-region passes only the accessible portion of the buffer to
the clang-format subprocess, not the entire buffer. Possible (untested)
solution: In clang-format.el, replace (call-process-region (point-min)
(point-max) …) with (call-process-region nil nil …).</pre>
