git recall --help argument issues error

[CharlesB2]

Instead of getting help, I get this message:

No manual entry for git-recall
See 'man 7 undocumented' for help when manual pages are not available.

git recall -h and git-recall --help works, though

git-recall 1.2.4 git version 2.7.4 on Ubuntu 16.04.4 LTS
