To get consistent formatting of subscripted variables inside Modelica source code, this involves changes in many places besides those where there used to be a \texttt

It was a mistake to think that the last entry in this list was a typo.  In a subsequent commit, I'll suggest writing it in a way with less risk of misinterpretation.

If we want boldface, we should use \mathbf.

This change is related to the other changes where operators with function calling syntax are mentioned.

The use of boldface was inconsistent with the rest of the listing anyway.

I skimmed the document, and as far as I could tell, this always gives a better result.

Similar sentences in other rows of the table are not written as separate paragraph, so this just makes the treatment equal across the table rows.

I've now taken the time to go through this chapter more carefully than the other chapters, hoping that this will be possible to use as example when later returning to do more careful cleanup of the other chapters.

A heading is a heading even without a trailing colon.  Maybe the colons were a rest from a time when these weren't normal headings, but some sort of boldface at the start of a paragram...
