![Matthew DeVore](/assets/img/avatar_default.png)
Allow combining of multiple filters by simply repeating the --filter flag. Before this patch, the user had to combine them in a single flag somewhat awkwardly (e.g. --filter=combine:FOO+BAR), including URL-encoding the individual filters. To make this work, in the --filter flag parsing callback, rather than error out when we detect that the filter_options struct is already populated, we modify it in-place to contain the added sub-filter. The existing sub-filter becomes the lhs of the combined filter, and the next sub-filter becomes the rhs. We also have to URL-encode the LHS and RHS sub-filters. We can simplify the operation if the LHS is already a combine: filter. In that case, we just append the URL-encoded RHS sub-filter to the LHS spec to get the new spec.
