[tex-hyphen] possible bug in Catalan hyphenation

[Claudio Beccari]

While reading the babel-catalan documentation i noticed this paragraph

To improve hyphenation we give the grave character (’) a non-zero lower 
case code; when we do that TEX will find more breakpoints in words that 
contain this character in its rˆole as apostrophe.
37 \addto\extrascatalan{%
38 \lccode‘’=‘’}
39 \addto\noextrascatalan{%
40 \lccode‘’=0}

1) The grave word should be repalced by acute.
2) Apparently the code snippet reported in the seocnd part of the copied 
snippet from  babel-catalan.pdf is the cause of the remarked bug. May be 
together with the lefthyphenmin=2 setting for the language

Apparently the bug vanishes if the activeacute option is selected, but 
with ths option in force the apostrophe should befollwed by an empty 
group (note 2 of the documentation) because the active single quote 
character is used to set the acute accent over the following vowel.

Moreover the babel catalan.ldf was last revised on 2005/03/29, therefore 
it not up to date with the LICR character representation that is being 
in force for the past four years; the arguments used inthe documentation 
for saving the different encodings from OT1 vs T1 and Type1 do not aply 
anymore.

The obvious suggestion would be to upgrade catalan.ldf and its 
documentation.

This is my analysis; it might be wrong, because I am not a Catalan 
writer and speaker, I can just read it.
