Note that these two lines of advice text are translated; see the
consequences below.

The {...} block is unnecessary, because there is only a single command
in there.

Please don't run git commands upstream of a pipe, because the pipe
hides their exit code.  Furthermore, put the sed script inside double
quotes, because the whole test is already in a single-quoted block.

I presume you wrote the test this way because you simply followed suit
of the previous test 'merge --squash c3 with c7', which did all the
same.  Bonus points for a preparatory patch that cleans up the
previous test ;)

But most importantly, here 'test_cmp' compares translated advice text
as well, which fails in the GETTEXT_POISON build.  Use 'test_i18ncmp'
instead.

Likewise.
