... a broken sentence in the middle? I would have expected the "not only"
followed by "but also"; the question is "but also what?"
Hopefully the benefit is not that it now allows all the other commands to
cause unspecified types of damage to the repository by following iffy
settings obtained from a broken configuration file.

The change to the test demonstrates the issue rather well. The check()
shell function does not check the exit value from "git config --get", but
in a real script that cares to check and stop on error, this change will
now let the script go on, leaving the breakage unnoticed. I suspect
command implemented in C, that call git_config(), will also have the same
issue, and I cannot convince myself this is a good change in general,
outside the scope of helping "git config -e".
But I may be being overly cautious.
By the way, why did you have to change s/echo/printf/? Can't you give two
lines in a single argument without "\n" escape?
