Hi,
org-babel-detangle is an interactive command but
M-x org-babel-detangle always replies "Detangled 0 code blocks"
This patch makes org-babel-detangle prompt for a source code file.
Obviously, I got bitten by this.
The patch contains
(user-error "Source code file does %S not exist" source-code-file)
so it may break code that uses org-babel-detangle in a loop.
I prefer an user-error, but others may not.
Regards -- Gerard

I suspect that you may have some misunderstanding about how
`org-babel-detangle' works. Its docstring says:
Propagate changes in source file back original to Org file.
So, it is expected to run from the tangled file; not from the Org file.

Yes, I misunderstood this and I see that my patch breaks this.
I think there is a typo in the docstring: "original to" must become "to
original"
so that it ends with "back to original Org file".

I have attached a modification of your patch. I think it is clearer
with
the risk of being too verbose, but the docstring width is < 80.
