"df" not deleting the searched charactor

Hi, Just noticed a problem: the command "df[char]" is not deleting the searched character [char] itself, making this command no difference to "dt[char]". This is pretty annoying because if the searched char is not being deleted, we can no longer use dot command to repeat the deleting operation. For example, I have this string: "foo-bar bar-foo fooa-bara bara-fooa should be deleted", I want to delete everything up to substring "should be deleted", I could use "df<SPC>" followed by dot command to repeat the deletion which is really handy. But now, since df<SPC> is not deleting the space itself, the dot command will fail, you have to type another "df<SPC>", sad. Don't you guys think this is worth fixing? Thanks, York
