Any super simple test we can add for these commands? You can use scr.columns/scr.rows to force the size of the RzCons so it is reproducible.

@ret2libc everything should be fixed now - the problem with pCA was that it was using pxA which changed behavior since - it limits itself to the block size in the short form (pxA) but works fine in the long form (pxAl).

The problem is that the second columns starts at 0x100003a64, but the first one ends with 0x100003a5c. So there is an instruction (0x100003a60) that is not displayed.

However... this is not strictly a problem with your conversion, so if you want go ahead but let's create an issue for this at least.
