Tim Allen a25cc215e8 Reference content goes in docstrings, explanations go in prose docs.
Also, make sure docstrings reference the prose docs, so people who stumble over
an interesting-looking command or option can find out more about it.

= Integrate with tools that check files for problems.
Many file-formats have "lint" tools that check for common problems and point out
where they occur. Most of these tools produce output in the traditional message
format:
----
{filename}:{line}:{column}: {kind}: {message}
----
If the 'kind' field contains 'error', the message is treated as an error,
otherwise it is assumed to be a warning.
The `:lint-buffer` and `:lint-selections` commands will run the shell command
specified in the `lintcmd` option, passing it the path to a temporary file
containing the text to be linted. The results are collected in the
`*lint-output*` buffer, and analyze it. If `toolsclient` is set, the
`*lint-output*` buffer will be displayed in the named client.
Each reported error or warning causes a marker to appear in the left-hand
margin of the buffer that was checked. When the main cursor moves onto that
line, the associated messages are displayed. If they get distracting, you can
turn off the markers and messages with the `:lint-hide-diagnostics` command.
You can also use `:lint-next-message` and `:lint-previous-message` to jump
between the lines with messages.
