Hi Ludo,

Thank you for the review!

Before pushing, I did some more tests to make sure it was still working.
When I did this, I noticed that read-line was no longer returning
strings that end in "\r".  This prevents child-shell-environment from
behaving correctly, since it incorrectly assumes that all the lines end
in "\r", stripping it off unconditionally.  In the past, I'm sure
read-line was returning strings that end in "\r".  I don't know what
changed, but I've attached a second patch that fixes this issue, also.

Unless you have more feedback, I'll go ahead and push both patches to
master in a few days.
