[Dev-luatex] Problem with hyphenation

[Javier Múgica]

I am using version 0.50.0, so I apologize in advance in case this has
already been fixed.

Input (utf-8, of course):

\font\tenrm=ec-lmr10 \tenrm
%\catcode`á=11  %doesn't make any difference
\hyphenation{cá-ma-ra}
\showhyphens{cámara}
\lccode`á=`á
\showhyphens{cámara}
\end

Output (log):

Underfull \hbox (badness 10000) in paragraph at lines 4--4
[][] \tenrm cámar-a

\hbox(6.81725+0.0)x16383.99998, glue set 9797.44336, direction TLT []

Underfull \hbox (badness 10000) in paragraph at lines 6--6
[][] \tenrm cá-ma-ra

\hbox(6.81725+0.0)x16383.99998, glue set 9797.44336, direction TLT []

The first case is wrong, but it is specially bad that luatex ignores
\lefthyphenmin
