It would be super helpful if multiple leactions could be provided in a logevents query. A typical example might be filtering letype=protect to include protect/protect and protect/modify but not protect/move_prot or protect/unprotect. Likewise for delete or block.
Presumably, if mixed options (e.g. protect/protect and block/block) were provided, that would imply multiple letypes could be provided, which is not currently the case. Alternatively, leaction could not supersede letype but be limited to subsets therein; that is, letype=block would only allow for leactions of block/block, block/reblock, and block/unblock.
