UID lookup is bad

[james-antill]

If you can't find a user you should use the UID not the empty string. Here:

logo-ls/formatterStuff.go

Line 88 in f6f6bee

o = ""

...then two lines later you should print u.Username not u.Name:

logo-ls/formatterStuff.go

Line 90 in f6f6bee

o = u.Name

...the first problem is repeated for group lookup error path.

You could also save a bit of space/time by creating the map as map[uint64]string and then testing before you have to do strconv.Itoa().
