Coreutils fixed it slightly better: it calculates the maximum width of
the abbreviated month names and pads to that (with a maximum of 5). In
particular, this ensures that the output does not change for locales
that have 3-character abbreviations, such as the POSIX locale. I think
this is valuable.

They also keep the list of month names from this calculation and they
say this speeds up ls noticeably compared to having strftime() expand %b
for every file.
