This causes the only byte in the file to be lost. For this issue #4

@guss77 is this a PR you could help review and create a new hotfix release once merged? Thanks!

@c3-robin - on the face of it this looks like a working solution(*). Can you also add a test that demonstrates that the problem has been resolved and protect against regressions?

*) I think that I'm not happy about the recursion anyway and maybe there's a better way to solve the problem by unwinding the recursion.

@c3-robin thank you for your contribution - I accepted the PR and the problem is now fixed in main.

I went ahead and wrote the unit test for that, mostly because I thought I can fix this another way and also get rid of the recursion, but this proved to be way too much code and not worth the trouble, and your simple solution is probably best.

Thank you!

Thanks for adding the test and bringing in the fix! I saw the original InputStream implementation of read did not use recursion as well, but noticed recursion was theoretically correct and had much cleaner code.
