John says that the front derailleur can move past the big ring--the issue is with the shifter--so I would doubt that having too wide a chainline is the cause.
The three things I would check: like Garth said, it could be an assembly issue with the shifter. Specifically, there is a washer that goes between the shifting mechanism and the pod that aligns the shifting mechanism and can limit the shifter travel if it is installed in the wrong orientation. It looks like this. <http://www.treefortbikes.com/product/333222402575/1511/Shimano-BS78-Bar-End-Rear.html?utm_source=google&utm_medium=cpc&scid=scplp333222402575&sc_intid=333222402575&gclid=Cj0KEQjwo-XIBRCOycL7hsuI_NoBEiQAuS6HtEja3CQW0xgS2Gjh0vONTwtpsfmc54P0cTdytekpR8IaAphL8P8HAQ> The square-shaped protrusion should point straight down. This topic has been discussed a few times around here so if you do some searching you might be able to find more information on it. Secondly, you mention that you changed from bigger to smaller chainrings over time. Did you move the front derailleur down the seat tube when you did so, to re-adjust it's clearance to the big ring? The closer to the chainrings the derailleur is, the more effective it will be. The shimano spec is that the outer plate of the front derailleur cage should sit about 3mm above the tops of the teeth of the big ring when in the middle ring. Finally, I would check the low limit adjustment. Is there excessive space between the derailleur cage and the chain in the lowest gear (small chainring, biggest cog) with no cable tension on the front derailleur? Since the low-limit screw kind of sets the tension zero point for the front derailleur, if it is too far out, then by tightening it you might gain some shifter movement at the other end of the travel. After checking the shifter assembly, derailleur position, and limit screws, I would make sure that i take all of the slack out of the cable with the shifter and derailleur it their initial positions to assure that no shifter movement is wasted in taking up slack. Barrel adjusters are your friend here, if you happen to have them on your downtube cable stops. Given the ubiquity of Shimano bar end shifters, sugino xd2 cranks, and all flavors of shimano front derailleur in our corner of the bike world, I would be surprised if there were some kind of compatibility issue here.
