And what did Pathfinder find exactly? I admit I only skimmed the fighter entry just now, but it looks to me like 'armour specialization' and 'weapon specialization' and 'bravery' are all the improvements he got. There's no sign of any 'alternatives' to choose between.
There are also tweaks in the actual feat chains the fighter has access to. Primarily in 3E, feat chains pretty much petered out at about 6th level. There's a bit more base variety for "combat tricks" and the chains now top out about 13th or so. One downside is that most non-fighters can still qualify for most of these feats, but the fighter will certainly be getting to them sooner.
Not big tweaks, but from what I've been playing with my group so far, the fighter is doing well - hard to hit and killing things fast. In our last game, the 5th level fighter handily took out a CR 7 ghoul cow (yes, ghoul cow) by his lonesome (and easily) in about 2 rounds of combat.
