Subject: [PATCH] t4062: use less than 256 repetitions in regex
OpenBSD's regex library has a repetition limit (RE_DUP_MAX) of 255.
That's the minimum acceptable value according to POSIX. In t4062 we use
4096 repetitions in the test "-G matches", though, causing it to fail.
Combine two repetition operators, both less than 256, to arrive at 4096
zeros instead of using a single one, to fix the test on OpenBSD.
