Does this file also need a whitespace cleanup?

Does this file also need a whitespace cleanup? 2 times yes. It's not the only file with tabs instead of spaces.

As I tried to explain in the commit message, a fall through would not be reasonable in this special case. Cheers, Stefan

Ah sorry, my comment was based on reading "omit break before default" in the commit message; tired, should've looked more closely. FWIW: Reviewed-by: Andreas Färber <afaerber@suse.de> Andreas

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. Signed-off-by: Stefan Weil <sw@weilnetz.de> --- ui/vnc-enc-hextile-template.h | 1 + 1 files changed, 1 insertions(+), 0 deletions(-)
