The bigger issue is that -search seems to blindly match the
msg body. It doesn't even do mime decoding. So for example the
body of my prev msg to nmh is base64 encoded (even though it
is plain text) and -search fails. Unless I specify a search
pattern of encoded text such as 9uIEJpZyBlbmRpYW!
pick(1) not doing MIME decoding is clearly a bug, and as far as I know
there has been no disagreement on that. The plan is to fix that in the
Great Mime Rewrite. Someday.
