There are some less subjective guidelines.  Asciidoc turns "--" into an
em-dash.[1]  In English, em-dash is almost always not surrounded by
spaces (it is in French, for example), while en-dash is spaced in
English when used instead of an em-dash.[2][3][4]

This means that it's all the other places that use " -- " with spaces
that are incorrect.

Indeed, correcting spacing around dashes is orthogonal.  Also, it might
not be very desirable to have so much churn for spacing issues.
