realpath error message from texdoc command

[Murray Eisenberg]

In TeXLive 2019, with the latest updates from CTAN applied in TeXLiveUtility, whenever now I execute the texdoc command, even though it works, I also get the error message:

	sh: realpath: command not found

This is under macOS Catalina (10.15.3).

What’s wrong?
