When I saw that this was a series with 10 patches (without reading
anything else) I expected that you had created a test-lib.sh helper
that allowed replacing a word in a string with another string, and
then the remaining patches were fixing the other tests that have
similar breaks when using "@" in the path.

(Heck, I'd even take a "test-tool replace-word <string> <word>
<replacement>" implementation to avoid all of these issues we have
due to using scripting languages that rely on special characters
to define the match and replacement operation.)

It seems like this isn't the last time we are going to have a
problem with string replacement like this, and having a well-defined
helper would go far.

The rest of the changes to the test script seem more complicated
than necessary for what _should_ be a simple problem.
