Hi Hilmar,

I just tried it on a MacOS running TeXLive 2018 with all current
updates, and it exhibits the same problem still:

~ $ texdoc -l number
47 results.  Display them all? (y/N) y
[and then lists just 46]

On TeXLive, texdoc reports:

~ $ texdoc --version
Texdoc 3.0

and tlmgr info texdoc reports:
installed:   Yes
revision:    47946
sizes:       doc: 197k, run: 113k, bin: 5k
relocatable: No
cat-version: 3.0
cat-date:    2018-06-06 17:29:57 +0200

So it's certainly not been updated there.

Best wishes,

   Julian
