-output_uri_replace regex is nearly impossible to use

After much frustration fussing, and a post to stack overflow, I finally found a syntax that would work:
"^.*(/[^/]+/),'$1'"

It turns out that you have to both wrap the whole thing in double quotes, and ALSO wrap the replacement string in single quotes. That's in a config file. I never got it working on the command line.

The error message is anything but helpful.

To me it looks like a bug, but in any case it should be documented properly, which it is not. A working example of regular expression replacement should be included in the documentation.

The above is a very simple expression that should be useful to discard everything up to the directory below, which is probably a very common use case. It shouldn't be so difficult to do that, and I shouldn't be forced to spell out the explicit path, as that solution is not portable.
