Subject: clang-format: Give clang-format-diff.py a -v option.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8f0a1a658d9db734f55a637d6b2b64a084653fe8;p=clang

clang-format: Give clang-format-diff.py a -v option.

With it, it prints the file being formatted. Apparently people are
formatting thousands of files and some progress indication is helpful.
