Setting the config option `blame.ignoreRevsFile` globally to eg
`.git-blame-ignore-revs` causes `git blame` to error when the file
doesn't exist in the current repository:
```
fatal: could not open object name list: .git-blame-ignore-revs
```
Instead, just skip over ignore-rev files that don't exist.
