Please be considerate to future readers of "git log" to help them avoid mistakes earlier commits made that caused you troubles.
This line by itself without any explanation of what was broken is quite useless as a commit message. What can the readers do? They'd go back and say "git show 480871e09" and then what? The test added or modified by the commit has been working quite well for others since it was made, so it is very likely the reader wouldn't be able to tell if anything is wrong in it.
You would help if you said what is different in _your_ environment from others who have happily been running and passing this test for others to understand and learn from your fix. What is it?
The "Adjust ... distro changes" in the title offers some hint but it could be more explicit. Please write something along this line instead.
Subject: t4014: git --version can have SP in it
480871e09e ("format-patch: show base info before email
signature", 2016-09-07) added a helper function to recreate the
signature at the end of the e-mail, i.e. "-- " line followed by
the version string of Git, using output from "git --version" and
stripping everything before the last SP. Because the default Git version string looks like "git version
2.10.0-1-g480871e09e", this was mostly OK, but people can change
this version string to arbitrary thing while compiling, which
can break the assumption if they had SP in it. Notably, Apple
ships modified Git with " (Apple Git-xx)" appended to its
version number. Instead, come up with the version string by stripping the "git
version " from the beginning.> Signed-off-by: Jeremy Huddleston Sequoia <jeremyhu@apple.com>

Please don't do this in your log message. These belong to your e-mail headers, not here.

Anchor the fixed prefix to the beginning, so that we can protect ourselves from another distro that would add "git version" in the middle of their arbitrary versioning scheme ;-). I.e.
sed "s/^git version //"
