Module escape 

Escaping for the three text formats apollo generates from paths it does not control: launchd plists, systemd units, and a generated shell script.

A workspace path is whatever directory the user pointed apollo at, and on Unix a directory name may legally contain <, ", $, a space, or a newline. Rejecting those characters outright is wrong — a macOS path with a space in it is entirely ordinary — so each value is escaped for the format it lands in. Only a newline, which no format can represent inside a value, is refused.
