output of uv pip compile has wrong syntax with extras

[alexeagle]

This may be a bug in uv, I'm not sure how to tell and haven't had time to dig in. Please forgive me filing an issue that's not well-researched :)

Installing a package with extras, such as etils[epath, epy] results in output from the pip_compile rule which has some whitespace issue.

Here's the patch one of my clients applied to workaround it:

If you need to overwrite requirements.txt it's a uv bug, I believe.
