This was not a bug, but it is not common practice to omit the break statement
from the last case statement before an empty default case.
Any change of the default case would introduce a bug.
This was reported as a warning by splint.

TABs vs. space looks odd. Does this file also need a whitespace cleanup?

2 times yes.
It's not the only file with tabs instead of spaces.

It was a fall through (so a comment would have satisfied static code
analyzers), but with the added 'break' it no longer is.
As I tried to explain in the commit message, a fall through would
not be reasonable in this special case.

Ah sorry, my comment was based on reading "omit break before default" in
the commit message; tired, should've looked more closely. FWIW:
