Missing indentation in the second line.

"failed to prepare" or some such instead of "${testfile}.exp"

typo: compileR

Write " = 0" instead of "0", since the latter matches
anything that ends in 0, like "= 10" too.

All those "set test_string" bits look like stale bits?  Should we
remove them?

Fix the nits above, and you're good to go for the whole series.
Please push.
