Thank you very much for this extensive feedback and for sharing your
scripts. I tried to set them up and make them work. I come to a stage
where I get the following error (which I seem unable to interpret):
mhnshow: option -c not recognized
usage: %s [-N prog] [-HDsw] arg [... arg] [-show]
filterproc: exit 2
writer process: signal 13 (Broken pipe: 13)
/usr/local/Cellar/nmh/1.7.1_1/libexec/nmh/mhl: exit 1
It seems to come about when I try to use your format filter. Would this
ring any bell? Or any other suggestions?
In any case many thanks,
Marc
