Oops, sorry about that!

So this is another bash 4 screwup! Second one I ran into today.

Not a coreutils bug.  There has been no change in this behavior in coreutils' printf:

$ /bin/printf --version | head -n1
printf (GNU coreutils) 6.10
$ src/printf --version | head -n2
printf (GNU coreutils) 8.1.2-f18ee
$ /bin/printf '%.*s\n' 3 -----
---
$ src/printf '%.*s\n' 3 -----
---

Rather, what you are probably seeing is that your current shell's printf built-in does not implement the same POSIX extensions as GNU coreutils' printf.

Using a coreutils 7.3, I discovered printf breakage:

The following should print 21 dashes.

printf '%.*s\n' 21 -------------------------------------------

It works if the * precision is literally replaced by 21, as in:

printf '%.21s\n' -------------------------------------------

Oops!
