[PATCH v3 0/2] t3700: modernize and fix exit code suppression

This is the third version to modernize t3700 and ensure git's exit codes are not suppressed in pipelines.

Changes in v3:
- Split the series into two distinct patches as suggested by Junio.
- Patch 1/2: Focuses strictly on breaking pipelines to expose git's
  exit status and simplifying 'wc -l' logic.
- Patch 2/2: Converts all remaining 'grep' and '! grep' calls to the
  modern 'test_grep' and 'test_grep !' helpers.
- Fixed trailer formatting in commit messages.

Siddharth Shrimali (2):
  t3700: avoid suppressing git's exit code
  t3700: use test_grep helper for better diagnostics
