Right.  Under 21.1.14 I don't see --with-file-coding available as a
configure option (when I run configure --help).  However a look into
the configure script itself shows that it's there.

I just fired up a 21.1.14 (no mule, no file-coding) to try to read an
encrypted message to check your fix and got this backtrace (lines
wrapped by me):

Which seems odd.  It works just fine in 21.4.6.

Hmm.  If "mail" is just signed the last one works fine.  If "mail" is
encrypted it barfs (the result of the previous command is empty,
which doesn't surprise me somehow :-), but if I decrypt mail first and
work on the decrypted output it works OK.
