[gradsusr] continue a line

[Kevin Huyck]

I didn't realize that. Thank you, Jennifer. I've tested this technique 
and it works in both examples below...

dwind = 'pow(ugrd_isbl(z-1)-ugrd_isbl,2) + '
'define dwind = 'dwind % 'pow(vgrd_isbl(z-1)-ugrd_isbl,2)'

dwind = 'pow(ugrd_isbl(z-1)-ugrd_isbl,2) + '
dwind = dwind % 'pow(vgrd_isbl(z-1)-ugrd_isbl,2)'
'define dwind =' dwind
