trivial error in hg/ssh/OSX page
https://confluence.atlassian.com/pages/viewpage.action?pageId=270827678 contains the text:
"If you are running OSX 10.6.8 or you can skip this step."
The "or" in this sentence is incorrect. I guess that it should be "10.6.8 or later". Similarly the following sentence may also need to be adjusted.
