Range patterns must not evaluate endpat until the range starts matching

[bertysentry]

The below awk script:

a++ == 2, a++ == 5

with this input:

1
2
3
4
5
6
7
8
9
10

should print:

3
4
5

But Jawk produces:

2
3

because it executes both begpat and endpat for each record.

The tuples must be updated to reflect this.
