I'd say about 65% of all men I've ever dated have done things like that. There are different levels, though. Some of them stop at opening doors, and some go as far as to stand up when I leave and return to the dinner table. Some always bring flowers, and some draw the line at carrying purses.
Some will offer you their jacket, and some will ask you if you'd like to go indoors (which is still polite, IMO, since it shows they're thinking about how comfortable you are).
I don't think it was ever indicative of what type of person they were or how nice they were--some people just weren't taught to do stuff like that. I like it though, and my Mr. Right will definately be a gentleman.
