Strip filter name from command before passing to filter function.

The new registration of in-process data filters (introduced in
f8ad3b76e923 & 11af38a592ae) failed to correctly strip the filter name
from its arguments before passing the "command" to the filter
function. Thus a registration such as

[decode]
*.gz = compress: -9

would result in the associated filter function being called with the
argument 'compress: -9' rather than just '-9' as expected.
