 wildcard allow us to load many rasters and it is very usefull to be able
 to use them with the "-k 100x100" option but there is no garantee that
 those many rasters will result in a coverage following rules 3 and 5 of
 regular blocking:

 3) The top left block must start at the top left corner of the extent.

 5) The extent field must be a simple rectangle (non-rotated).

 It might be very difficult to verify those conditions so it might be
 better to set regular_blocking to FALSE when using wild card.

 I saw that it is also impossible to use -k when two -r options are used.
 Again the rule should be that we can use -k but because there is many
 rasters we can not assume they will end up in a coverage following
 regular_blocking.
