* Preserve paragraph breaks in the KCL docs
The KCL docs on the website are hard to read, because they concatenate all
the paragraphs in my nicely-formatted docstrings in the stdlib functions
into one big paragraph. PR should fix this.
* Fix arc docs being split into two lines
The 'summary' section of the docs has a maximum line length, and if you
go over that length, your summary gets split into two lines weirdly.
Makes the arc docs shorter, so the summary is back to one line like
it should be.
* Update docs for pattern transform
