Log Message:
make: restructure code in ParseVarname to target human readers

Breaking the loop once for depth == 0 and once for depth == 1 was
unnecessarily confusing, as was the nested 'if'.  Start counting with 0
since there is no reason to start at 1.

Evaluating the common subexpression '*p == endc' is left as an exercise
to the compiler.

No functional change.
