mandoc validation thinks CONTEXT is in the wrong place
mandoc's lint has different ideas about where the CONTEXT section belongs relative to everything else. It appears that this is because it's been inserted right after the DESCRIPTION section. However, in all of our manual pages, it comes after RETURN VALUES and ERRORS, but before SEE ALSO. It appears that moving the section down and fixing up the corresponding array of function names changes this, though I'm not 100% sure if this was an intentional change or just something that was missed due to the small amount of section 9 manual pages. I only noticed this when writing a new one.
