Highly appreciated -- I'm busy this week, but I'll take a look
in the coming week.

I'll update it. There are a few changes in flight that are being
worked on, and once I commit them to 9front I'll sync back.

[9fans] kerTeX: LaTeX fixes

[tlaronde]

FWIW, for LaTeX users (I'm not), I had made a blunder in the latex.sh
recipe preventing the installation of a part of the (huge) psnfss font
collection. It has been corrected.

Since a LaTeX user hit a capacity limit, I have also increased the 'BIG'
version of the prote engine.

One thing that may hit other (not LaTeX) users: if a line was not
terminated by a newline, but it was the end of the file, it was an
error. After a multiplication of files not ending with a newline, I have
modified the input routine to consider the eof to be a valid end of
line.

Everything is online.

Hi ori, this patch applyes to the sources served at 9front.org.
By the way, do you plan to keep in sync
http://only9fans.com/ori/git9/HEAD/info.html or should I forget
about that repo?

Regards,
adr.
