* Drop pointless local variable in snprintf callbacksPhil Sutter2021-03-151-2/+2
| | | | | | | | | | A common idiom among snprintf callbacks was to copy the unsigned parameter 'size' (or 'len') into a signed variable for further use. Though since snprintf() itself casts it to unsigned and SNPRINTF_BUFFER_SIZE() does not allow it to become negative, this is not needed. Drop the local variable and rename the parameter accordingly.
