Protecting users of obsolete API (pre AssetInfo)

[peterhoward42]

I wonder if you would consider a change to AssetFS to protect others from a problem I had, and took quite a while for me to find the root cause?

I have a project that used your older API (without the AssetInfo field).

http.Handle("/", http.FileServer( &assetfs.AssetFS{Asset: Asset, AssetDir: AssetDir}))

My project still compiled fine with the newer versions of AssetFS code despite what is now a missing initialiser, but hits a null pointer error at run time at line 148 in assetfs.go with this:

if info, err := fs.AssetInfo(name); err == nil {

All fine now I updated my call of course, but shame to require others who hit the same problem to dig into AssetFS source to work out what's happening.
