cmake-format v0.6.9

The parser now performs token look-ahead when parsing a comment within
astatement. This allows it to determine whether a comment belongs to the
currentsemantic node or one higher up in the tree (previously it would
assign allcomments to the most recent semantic node). This should
prevent some unusualindentation of comments within deep statements.

Some cmake-lint crashes have been fixed and the test coverage has
increasedsignificantly. There are still some outstanding issues but it
should crash lessfrequently and with more helpful information.

Detailed documentation for configuration options is now
generatedautomatically, including default value, command line syntax,
and exampleconfiguration file entry.
