I think "make style" and the EditorConfig file are complementary.  "make
style" autoformats code into a diff.  I agree that if we always used
clang-format to format code, then this would be a non-issue in the
EditorConfig file, since we'd just tell people to format their code and
be done with it.  However, we don't automatically do that, so I think
this still has value.

(I am having trouble getting make style to work, though, because it
seems to invoke clang-format as a git subcommand, and I don't think that
works.  I may send a patch.)

Even if we did that, we couldn't do it for Perl, because the tidy tool
for Perl, perltidy, produces different output depending on version.  I
expect we'll have little success in trying to standardize on a given
version.

The EditorConfig file applies to a variety of formats and is designed to
set default editor settings (which users *can* override if they choose).
It applies to any file pattern; for example, as Taylor pointed out, we
could use it to recommend 72-character lines in commit messages.

I agree that maintaining more files is a hassle, but personally, I think
it quite unlikely that we're going to change the Git style, so I feel
the maintenance is fairly low.
