[PATCH 0/3] dropping "verbose" test helper function

I happened across an instance of the "verbose" helper function in a test recently. I think it's clear we prefer the "-x" tracing to it these days, and we've been slowly removing instances. This series gets rid of the last few.

The actual change (and rationale) is in patch 3. Patch 1 just fixes pipe problems on lines we'll be touching patch 3, and patch 2 is a cute optimization enabled by patch 1. I don't think any of it should be very controversial, but it can all be split up if need be.

  [1/3]: t7001: avoid git on upstream of pipe
  [2/3]: t7001: use "ls-files --format" instead of "cut"
  [3/3]: t: drop "verbose" helper function
