I haven't written code for plan9, so this is my own taste about plan9
coding style.

for ( i=0; i < nrows; i++);

or

for (i=firstrow; i <= lastrow; i++);

"i" is only an iterator variable, as used in the sigma notation for summation.
What has meaning to me is the condition or initialization variable (nrows,
firstrow, lastrow...)

This style looks standard.
