The change is purely cosmetic at this point in time, but it does highlight the change done in lib/string.c for match_string(). Particularly for this change, if a regname is removed (replaced with NULL) in the list, the match_string() helper will continue until the end of the array and ignore the NULL. This would technically allow for "reserved" regs, though here it's not the case.
