[Pan-users] Multiline custom headers?

[David Sewell]

When creating a posting profile, is there any way to pass a multiline
extra header that Pan will handle properly?

I've got pan2 0.125 installed and wanted to add an X-Face header (yes, I
am old school). X-Face headers are encoded as a 72-character first line
plus one or more lines of up to 79 characters, with newlines and
whitespace as separators.

I can paste one into the form, but it is saved to posting.xml as
garbage.

I didn't have any luck either editing posting.xml by hand and attempting
to encode the newlines as 
.

Is there a way to do this?
