Running `git` commands inside command substitutions like
test "$(git rev-parse A)" = "$(git rev-parse B)"
can hide failures from the `git` invocations and provide little
diagnostic information when `test` fails.
Use `test_cmp` when comparing against a stored expected value so
mismatches show both expected and actual output. Use `test_cmp_rev`
when comparing two revisions. These helpers produce clearer failure
output, making it easier to understand what went wrong.

Git supports creating additional commands through aliases, and through
placement of executables with a "git-" prefix in the PATH.
This information was not easy enough to find - users will look for this
information around the command description, but the documentation
exists in other locations.
Update the "GIT COMMANDS" section to reference the relevant sections,
making it easier for to find this information.
