This one indicates that you'd made local changes to your table which collided 
with changes made to the copy in the repository. When such a collision happens, 
svn adds lines like that to the file showing which are your changes and which 
are repository changes.

Those are because it's become ambiguous to start a line with a character value 
since brltty now supports not only characters in the local character set, but 
also Unicode characters. Characters in the local character set are defined with 
the keyword "byte", and Unicode characters are defined with the keyword "char" 
(in ISO-8859-1, or Latin1, of course, it happens to be the simple case where 
both are the same). While the "byte" keyword has always been supported, it was 
optional (and rarely used) when brltty only supported local characters.

While I think we're done making huge changes to the text tables, you may wish 
to take advantage of a new feature in order to better protect yourself from 
future changes of this nature. Text tables now support the include directive, 
so it'd probably be best to put your local changes into a text subtable (the 
extension we use for that is .tti) and then to simply add an include of your 
subtable to the end of the main table.
