[PATCH] t4202-log.sh: Test git log --no-walk sort order

[Michael J Gruber <git@drmicha.warpmail.net>]

'git log --no-walk' sorts commits by commit time whereas 'git show' does
not. Document this by two tests so that we never forget why ba1d450
(Tentative built-in "git show", 2006-04-15) introduced it and
8e64006 (Teach revision machinery about --no-walk, 2007-07-24) exposed
it as an option argument.

Not much to add here, besides the fact that the actual test target
should justify testing log as well as show here.

Based off master.
