[Nmh-workers] mhshow/test-charset failures in nmh-1.7 (`Can't convert ?us-ascii to UTF-8')

[Leonardo Taccari]

Dear nmh community,
first of all thank you very much for working and releasing nmh-1.7!

In the process of updating mail/nmh package in pkgsrc I've rerun
the tests (as I've done periodically for the three 1.7 RCs) and with
nmh-1.7 I have found this - maybe - new test failure (this is on
a not-so-current NetBSD-current amd64 8.99.1, not sure if that
matter though, it's the same version where I have run the previous
test for 1.7 RCs):

 *** .../test/testdir/21398.expected        Mon Nov 20 13:27:20 2017
 --- .../test/testdir/21398.actual          Mon Nov 20 13:27:20 2017

 + mhshow: Can't convert ?us-ascii to UTF-8
 + mhshow: unable to convert character set from ?us-ascii, continuing...
   [ part  - text/plain -   0B  ]

 ./test/mhshow/test-charset: test failed, outputs are in 
.../test/testdir/21398.expected and .../test/testdir/21398.actual.
 first named test failure: replacement character in parameter value
 FAIL: test/mhshow/test-charset

It seems that the unexpected output `+ mhshow: ...' are printed to the
stderr but also ends up in the `*.actual' file.

Is this (accidentally) expected, should I try to investigate if I
have some weird local configuration that is picked up (that's
probable! :)) or, can you reproduce it as well?

For completeness I will attach also the 21398.{expected,actual}
files but I'm pretty happy to help debugging/testing possible patch
so feel free to contact me if you can't reproduce that!


Thank you for the attention and thanks again for nmh-1.7!
