Please check output from "git shortlog --no-merges -100" to see how
your titles play well with others.  We typically prefix the title
with a specific area, a colon, and a sentence that does not begin in
a capital letter and does not end with a full-stop.

Hmph, I do not immediately see the point of having the helper in
test-lib-functions.sh, though.  This helper looks more or less
specific to this test script.

In any case, I think addition of the "test_mode_in_index" helper and
conversion from case/esac to the helper should be a separate patch
from what this patch wants to do, which is to merge two more-or-less
redundant tests into one.

Thanks.

[PATCH v2 2/3] Make test t3700-add.sh more robust

[Ingo Brückl]

Don't rely on chmod to work on the underlying platform (although it
wouldn't harm the result of the '--chmod=-x' test). Directly check the
result of the --chmod option.

Add a test_mode_in_index helper function in order to check for success.
