Why class CovLine initialize count = 1

[cheneylz]

From class CovLine

// we start with all lines having been executed, and work
// backwards zeroing out lines based on V8 output.
    this.count = 1

This will cause all count = 1，even though code not covered；

================================

Maybe in this part set count = 0？

v8-to-istanbul/lib/v8-to-istanbul.js

Line 203 in 46b9724

if (startCol <= line.startCol && endCol >= line.endCol && !line.ignore) {

However, if there is no uncovered data in the range（block.ranges）, the original count=1 will not be set to 0.
