lacheck is confused when curly brackets are inside a \newcommand

[Karl Berry]

Hi Michael,

    have to figure out where to go from line 391 of lacheck.l
    (https://tug.org/svn/texlive/trunk/Build/source/utils/lacheck/lacheck.l?view=markup#l391).

Thanks for that pointer. Maybe we can just add a \* in the right place
in that pattern. I'll give it a try when I have a chance.  What platform
are you on? Conceivably I could send you a test binary.

Thanks,
Karl
