[bug-gawk] 0 is invalid as number of arguments for tolower

[Hermann Peifer]

Hi again,

I assume I am simply to naïve in assuming that the below would ever 
work. gsub() knows what `&' is about, but tolower() doesn't and will 
never learn, so this is a feature (and shouldn't be sent to bug-gawk in 
the first place ;-), correct?
