Subject: checkpatch: better --fix of SPACING errors.
Previous attempt at fixing SPACING errors could make a hash of several
defects.
This patch should make --fix be a lot better at correcting these defects.
Trim left and right sides of these defects appropriately instead of a
somewhat random attempt at it.
Trim left spaces from any following bit of the modified line when only a
single space is required around an operator.
