sh file paths with spaces are not handled

[folderol4]

Testing running this in a repo with the following path: /src/content/space space/super-bad.sh

Results in the following:

src/content/space: src/content/space: openBinaryFile: does not exist (No such file or directory)
space/super-bad.sh: space/super-bad.sh: openBinaryFile: does not exist (No such file or directory)

It appears spaces are not handled.
