Checkstyle: Relax line length check for Javadoc comment lines containing command
Checkstyle: Relax line length check for Javadoc comment lines containing command

Summary:
Javadoc commands like {@code ...} cannot be word-wrapped
across lines.  Unfortunately, sometimes these need to be very long,
like this example from `AppleSdkPaths`:

  /**
   * Absolute path to tools and files which depend on a particular SDK on a particular platform.
   *
   * Example:
   *
   * {@code /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator8.0.sdk}
   */

Checkstyle currently raises a lint error for lines like this, even
though there is no alternative to using a long line.

So, this diff adds a checkstyle exception to Javadoc comment lines
containing a {@foo} command.

Test Plan:
Applied above example to repo. Ran `ant checkstyle`,
confirmed lint error for line length. Applied fix, ran `ant
checkstyle`, lint error was gone.

Manually made a very long comment line in local repo which didn't
contain a Javadoc command, confirmed `ant checkstyle` still raised
a lint error.
