[PATCH v3 1/2] editorconfig: provide editor settings for Git developers




Contributors to Git use a variety of editors, each with their own
configuration files.  Because C lacks the defined norms on how to indent
and style code that other languages, such as Ruby and Rust, have, it's
possible for various contributors, especially new ones, to have
configured their editor to use a style other than the style the Git
community prefers.

To make automatically configuring one's editor easier, provide an
EditorConfig file.  This is an INI-style configuration file that can be
used to specify editor settings and can be understood by a wide variety
of editors.  Some editors include this support natively; others require
a plugin.  Regardless, providing such a file allows users to
automatically configure their editor of choice with the correct settings
by default.

Provide global settings to set the character set to UTF-8 and insert a
final newline into files.  Provide language-specific settings for C,
Shell, Perl, and Python files according to what CodingGuidelines already
specifies.  Since the indentation of other files varies, especially
certain AsciiDoc files, don't provide any settings for them until a
clear consensus forward emerges.

Set the line length for commit messages to 72 characters, which is the
generally accepted line length for emails, since we send patches by
email.

Don't specify an end of line type.  While the Git community uses
Unix-style line endings in the repository, some Windows users may use
Git's auto-conversion support and forcing Unix-style line endings might
cause problems for those users.

Finally, leave out a root directive, which would prevent reading other
EditorConfig files higher up in the tree, in case someone wants to set
the end of line type for their system in such a file.
