x="":y="" are invalid arguments. They must be valid, even if they not
gonna be used later.
now it works. Thank you!
Should be added to sendcmd documentation:
-- An example which shows where to insert the sendcmd filter, if the
target filter has more than one input.
-- All arguments of filters must be initialized with valid values, even
if they are never used because sendcmd overwrites them.
patch welcome
sorry, I never figured out how git works. Too complicated for me.
Another idea: Could sendcmd be modified so that it can be inserted at
any place in the filter chain, regardless of the number of inputs?
