I had posted this to comp.mail.mh, but haven't received any replies.
I hope no one minds if I ask again here:
| It's kind of odd that mh-format supports cur as a special function
| rather than a general function that tests if the current message is a
| member of a given sequence. In other words, I'd like to be able to
| write a scan.format that includes something like
| %4(msg)\
| %<(inseq cur)+%| %>\
| %<(inseq unseen).%|%<{replied}-%|%<{encrypted}E%| %>%>%>\
| ...
|
| Is there some reason that the formatting code avoids reading the
| sequence files, or is it just historical?
