bug#62515: Bug in pr

[Luke (gmail)]

When the page length is less than 10, pr does not output a header, even 
one that is explicitly supplied.

Stated another way, when page length is <= 10, there is no way to 
counter implicit -t/-T.

Stated another way, -t/-T always (silently) overrides -h, and there is 
no option to force a header.

This is in $ pr --version
