After we finish reading a chunk of data from the file stream we know how many digits we need in the line number column to show the current maximum line number. If our line number column isn't wide enough, we should expand it out to the correct width. Any file over our default allowance of 5 digits (99,999 lines) is so large that the slight UI "glitch" when we widen the column out is trivial compared to the time it will take Git to fully do the annotations.
