IIRC, my point was to avoid adding *big* if/else branch which will be likely
to introduce untested code paths.
I don't think there would be a way to go without if/else or try/except as
long as we use the low-level filelog API for performance reasons. Perhaps,
we'll have to catch WdirUnsupported error to fall back to the filectx API.
```
try:
flog.read(fnode)
except error.WdirUnsupported:
ctx[fn].data()
```
