# We avoid using "nametemplate" because it uses a predictable filename
# under /tmp. The "needsterminal" forces mutt to wait until you press
# Return before it deletes the file; otherwise, Epiphany will notice
# that it's gone and show you nothing. Finally, the call to "tidy"
# ensures that Epiphany will not balk at the invalid HTML prevalent in
# emails. We ignore errors in "tidy" because we expect a bunch of HTML
# warnings to remain. The weird subshell construct is there because I
# don't know how to escape a semicolon.
