Sorry, I should have commented here after --- line what changes were
proposed by this set of amends.

I noticed that the lack of "\n" at the end was merely copied from the
previous existing test (i.e. "-c with with changed comment char"),
which was already wrong the same way, so I kept that part as-is.

Running "stripspace" in a subdirectory is to avoid the ".git/config
was read without repository discovery as long as the command runs at
the top-level of the working tree" accident so that this highlights
the breakage with or without Peff's b9605bc4f2 ("config: only read
.git/config from configured repos", 2016-09-12).

Removed from here is a leftover debugging bit (grep "^#"
edit-script).
