Note that '\x3b' ⇔ '\\x3b', since fish does not recognize '\x' as a known escape: however since a literal backslash is intended, it's clearer to write it explicitly.

This implements the string escaping scheme documented for the "E" (executed) and "P" (property KV) codes. This is "pure" fish and relies on no external utilities.
Although currently the only "required" escapes are backslash, semicolon, \x07, and perhaps newlines, this conservatively escapes all non-alphanumeric characters.
Backslashes are doubled, non-alphanumerics are hex-escaped.
