Is there an easy way to have csh foreach loops that don't complain if the
pattern given does not match any file, as may occur in the inner loop of this
bit of code:

foreach font (*.tfm)
    set fontname = `basename $font .tfm`
    foreach size ($fontname.*pxl)
    ...
    end
end

I've tried 

foreach size (`ls -1 $fontname.*pxl`).  

This stops the script from aborting, but still gives me the stupid 'No match'
message.  Gee, even FORTRAN does zero-trip DO loops these days...
