Disabling shell-escaping?

[DuimTechniek]

I was debugging a problem I had with files not uploading, and in the end it turned out to be an incorrect password.
I had a password with a "$" in it which was escaped to "\\$".
For testing I just disabled the escape entirely by returning the command without escaping and suddenly my files were uploading.

This means that in my specific situation it turned out that the "$" didn't need to be escaped at all.

My question is: is escaping needed at all? And if it is, may I suggest an option to disable escaping? I'd be happy to implement that and make a PR.

I see there is already a PR open for almost 2.5 years describing my problem: #70
