+tc_stab.c: small fixes to commandline help
+
+
+tc_core.c:
+As kernel part of things relies on cell align which is always set to -1,
+I also added it to userspace computation stage. This way if someone
+specified e.g. 2048 and 512 for mtu and tsize respectively, one wouldn't
+end with tsize supporting mtu 4096 suddenly, New default mtu is also set
+to 2048 (disregarding weirdness of setting mtu to such values).
+
+
+Unless I missed something, this is harmless and feels cleaner, but if it's
+not allowed, documentation will have to be changed back to 2047 + extra
+explanation as well.
