[luatex] query the value of \hyphenationmin

[David Carlisle]

Should the new \hyphenationmin be usable with \the and \showthe, like
\lefthyphenmin?

Currently if I want to see the current effective value I get from


\show\lefthyphenmin
\showthe\lefthyphenmin
\show\hyphenationmin
\showthe\hyphenationmin


> \lefthyphenmin=\lefthyphenmin.
l.4 \show\lefthyphenmin

?
> 2.
l.5 \showthe\lefthyphenmin

?
> \hyphenationmin=\hyphenationmin.
l.6 \show\hyphenationmin

?
! You can't use `\hyphenationmin' after \the.
l.7 \showthe\hyphenationmin

?
