Hi Jean, thanks a lot, your advice led me to the success!

I took this version.  I also omitted "-jobname prv_testmylátex" since
the original AUCTeX code doesn't have that part.  Do you recommend to
restore them?

I used the form "&prv_testmylátex" instead of -fmt="prv_testmylátex.fmt"
following the original AUCTeX code.  I expect this is harmless.

Thank you very much for your all valuable works!  I'll test this with
other cases (TL2017, file names with space, on w32 platform) and propose
to commit again.

For those interested in, the current tentative patch is attached below.
