Then as I said maybe you should make them to work in a useful manner =
;-) I'd
say your use case requires <tailfilter lines=3D"-2" />, which gives you =
the
tail of the file, minus the top 2 lines. <headfilter lines=3D"-2" /> =
would of
course yield the entire file minus the bottom 2 lines. Seems like a =
natural
extension of these filters, consistent with their Unix brethren. --DD

They work ... but not like hoped :-(
<headfilter> with negative lines-attributes gives nothing and
<tailfilter> with negative lines-attributes gives the whole file.
