Bikeshed will automatically handle a few typographic niceties for you, ones that it can reliably detect:

* Possessive apostrophes, and most contraction apostrophes, are automatically turned into curly right single quotes (`’`).
* Ending a line with `--` will turn it into an em dash (`—`) and pull the following line upwards so there's no space between the surrounding words and the dash.
* Ending a line with `--` will turn it into an em dash (`—`) and pull the following line upwards so there's a space between the surrounding words and the dash.
