To avoid misunderstanding, I am not against having unit tests when
they are appropriate. What I am against is to have only unit tests,
especially when the effect of a bug (and its fix) can be tested with
externally observable behaviour. The latter gives us a better sense
of the real-world impact (e.g. if run_command would spawn the given
command via shell using the 'sh -c "... stringified command and its
arguments ..."' idiom, it may be done with the function we fixed
here, which would mean that the user cannot pass '' as an argument
to that codepath), while a unit test gives readers "ok, the function
behaves that way now" alone, without answering "then what?  What
difference does this fix make to my use of Git as a whole?".

In any case, thanks for an attempt to fix.
