- This minimizes the number of reads from git; each logged value is read

{- Streams the git log for a given key's location log file.

-
|
|
- This is complicated by git log using paths relative to the current

|
- directory, even when looking at files in a different branch. A wacky
|
|
- relative path to the log file has to be used.
|
|
-
|
|
- The --remove-empty is a significant optimisation. It relies on location
|
|
- log files never being deleted in normal operation. Letting git stop
|
|
- once the location log file is gone avoids it checking all the way back
|
|
- to commit 0 to see if it used to exist, so generally speeds things up a

|
- *lot* for newish files. -}
