[GSoC PATCH 00/16] Microproject: avoid suppressing git's exit code

Piping git command output directly to subsequent command (eg. grep) hides the exit code of git behind the pipe. A crash in git would go unnoticed because the shell only sees grep's exit code.

This series extends the same fix to 16 more test files, following the approach introduced in t8003 [1] (redirect output to a temporary file, then use test_grep on that file).

Note: t2206 is a special case -- some tests cd into a subdirectory
that is itself a git repo and run 'git add .' on the whole working
tree.  To prevent the temporary file from being accidentally staged,
it is written as '../actual', outside the inner repo.
