texdoc error about realpath

[Bruno Voisin]

Since applying TeX Live updates this morning, texdoc is returning the error message

sh: realpath: command not found

It's still working (the required doc opens up as expected), but there's this message every time.

The above on the Mac (macOS 10.15 Catalina) with MacTeX 2019 updated via TeX Live Utility (a Mac version of tlmgr).

I'm reporting this here after seeing <https://tug.org/pipermail/tex-live/2020-February/044664.html> which seems to say texdoc has just been updated.

Regarding the version:

% texdoc --version
sh: realpath: command not found
Texdoc 3.2 (2020-02-02)
[...]
