"display-filters" in pine 4.33

[Dave Hunt]

For those looking to filter such things as "charset" warnings from your 
displayed mail, have a look at the help for the configuration item 
"display-filters".  Looks like you can specify "trigger" text in the 
message, and a command (e.g. an alternate viewer) to invoke when the text 
is present.  "charset" is one of the examples given in the help.  I found 
other neat things there, too.

Cheers,
