[PATCHv5 8/8] add tests of commit --squash

["Pat Notz" <patnotz@gmail.com>]

t7500: test expected behavior of commit --squash
t3415: test interaction of commit --squash with rebase --autosquash
t3900: test commit --squash with i18n encodings

Signed-off-by: Pat Notz <patnotz@gmail.com>
---
As noted in the cover letter, one issue which limits the testing is
that rebase --autosquash does not (yet) consider encodings when
comparing commit subjects.  So, we can't test the case of a fixup! or
squash! commit having a different encoding than the commit with which
it will be combined.
