PrintSmallInt() expects values in the 0-999 range, but the in+1 may produce
1000 here. This is invalid and it either asserted, or outputted an empty
string.
Workaround by simple outputting "1000" as the value here.
This function is only used in context of printing time, and only in specific
context. The end result will be that values like "1000 us" or "1000 ms" may
appear, where they would be otherwise shortened to "1 ms" or "1 s". This may
be a bit unusual, but is acceptable, as the real time value has not yet
crossed the threshold required for such shortening.
