Indenting a list relative to the previous paragraph creates
a blockquote. Combined with the natural list indent it results
in an overly large left margin.
Covers almost all blocks containing actual code, except:
* Parsed-literal blocks can't be highlighted, including many command
summaries and substitution-heavy docs like find_... commands.
This is a Sphinx limitation.
* Code with errors, like CMP0049, DEPLOYMENT_ADDITIONAL_FILES,
DEPLOYMENT_REMOTE_DIRECTORY, @PACKAGE_INIT@ substitution in the
tutorial, bracket arguments/comments in cmake-language.7 and
cmake-developer.7.
* FindQt4 module, which needs reformatting.
The documentation fix commit 04a11f16ba (CSharpUtilities: Fix
documentation, 2017-03-15, v3.8.0-rc3~17^2) introduced a cross-reference
to the function being documented. Fix it.
Issue: #16711
