[tex-eplain] Problem with usepackage

[Karl Berry]

Hi Fred and all,

    +%% From base/latex.ltx
    +\def\@parse at version#1/#2/#3#4#5\@nil{%
    +\@parse at version@dash#1-#2-#3#4\@nil
    +}
    +\def\@parse at version@dash#1-#2-#3#4#5\@nil{%
    +  \if\relax#2\relax\else#1\fi#2#3#4 }
    +

I installed this change and uploaded 3.11 to CTAN. (It will take a day
or two to get through the process.)  No other changes to the code.
Hope it flies ... --thanks again, karl.
