For the sake of readable diffs this change is done separately from the previous commit and it changes all man page headers to: - Use correct syntax \fB and \fR to make titles bold instead of previous capitalized version that had no effect - Omit unnecessary \&. syntax, works fine without it - Bump version to 10.11 Ideally the version would automatically be inherited from the build/release, but for now at least update it manually to match what is in the VERSION file of this release branch. All new code of the whole pull request, including one or several files that are either new files or modified ones, are contributed under the BSD-new license.
