You can also edit before resaving if you desire.

You'd open an AVI and use the 'File/Append Segment' menu to append another AVI to the open one(s). You can join AVIs with VirtualDubMod or VirtualDub2 and control the interleaving.

I don't know if ffmpeg is telling you the input is non-interleaved or if it's the output, although interleaving requires a bit more 'overhead' so if the file size has grown it suggests the input was non-interleaved but the output is interleaved. Interleaving is used because it makes seeking much faster and the player doesn't need to jump back and forth in the file to decode it. My understanding is non-interleaved means the AVI would contain all the video frames in succession and then all the audio. Ie some frames of video, then some audio, then more frames of video and so on. 'Interleaved' means the video and audio are interleaved.
