It looks like it will fail if you use windows line endings. Based on quick research, pscp keeps the original line endings. I suspect pscp downloads with unix line endings, and your text editor changes them to windows line endings, and then pscp sends it back as windows line endings.

I've successfully done this with filezilla, which will change line endings from unix to windows when transferring to windows and back to unix when transferring to unix. Alternately you can use a text editor that doesn't mess with the line endings.
