[tex-live] tlmgr w/ --machine-readable uses incorrect file descriptor

[Yudai NAKATA]

Dear Norbert-san,

I had to apply the patch directly in TEXMFDIST, which shouldn’t be
manually edited,
for some reason (possibly due to module structure), but I confirm the
patch works
as I expected.

Thanks for your prompt fix.

Best regards,
Yudai Nakata
