Comment 3 for bug 1916754

Here's a fix:

https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1916754-grid-row-numbers-over-100

This patch accommodates 3-digit numbers but not 4-digit numbers. I wasn't sure if that use case was common enough to warrant carving out the space.
