What is "the issue"? And in which way would an escape hatch help us here?
We would have to apply a patch anyway after a glitch like this shows up,
because disabling path mangling whole-sale (if there were a method --
there is none currently) is a no-go in the context of our test suite, let
a lone in our scripted tool set.

When "foo=/" appears on the command line, the most obvious interpretation
of the slash for a program without mind-reading mode is that it is an
absolute path, and then path mangling must happen (if and only if the
invoked program is a non-MSYS program such as git).

No, generally, path mangling is a service for the user.
