Fixes #291

Does this close any currently open issues?

#291

[BrandonCsSanders]

Earlier versions used echo for both decryped and current ... so did not show a diff because both had the extra newline. The switch to using $path rather than echo-ing the content is what surfaced this issue.

@BrandonCsSanders can you please re-create this branch based on the master branch?
The docs in 2.4 aren't up-to-date, new branches should be cut from master.
(The current docs say this: https://github.com/sobolevn/git-secret/blob/master/CONTRIBUTING.md#branches )

I'm not sure this is an issue in git-secret master.
Can you confirm it is still an issue with a self-test in master?
I didn't spend a whole lot of time on it but I couldn't reproduce the underlying issue: See PR #293

[joshrabinowitz]

I figured out the issue, it is explained in #291

Closing this PR as this issue is fixed in #293
Thank you so much for bringing this to our attention, and submitting this PR, @BrandonCsSanders
