compression: display compression level in debugformat Now that we have options to control the compression level, we teach `hg debugformat` about them. This is a useful information when comparing repositories. Note that we have no trace of the compression level used to store existing deltas. Actually, it would even varies from one delta to another. So we display the currently set value.
