Looks like I spoke too soon.  It worked on the test message I was
using, but running the macro on other signed messages it doesn't
work!?  Both messages are by the same author.  I'll have to tinker
some more.

The error message spreads text all over the screen so it's hard to
make out what the error is.  I think this means the error is from
the pipe, and have to ctrl-l to refresh the display.

Do you know how to catch what the error is?
