I have tried the converted maps: They are OK! So maybe just
the return value is reverted (it simply shouldn't print above warning).
Can't see any problems except the confusing warning with your updated
Re-running it is o.k. as well:
Skipping raster aspect at demomapset -- Not LZW compressed
Skipping raster slope at demomapset -- Not LZW compressed
So, if you revert the if-clause (or whatever) for the WARNING,
I think r.lzw2z is working well.
Continuing to convert 1000s of maps... :-)
