[PATCH 14/17] new: Cleanup. De-duplicate file name removal code.

[Austin Clements]

Previously, file name removal was implemented identically in two
places.  Now it's captured in one function.

This is important because file name removal is about to get slightly
more complicated with eager tag synchronization and correct removal
atomicity.
