Description

I tried this command:

cargo doc

I then pressed ctrl-c to stop it. I then re-ran it.

I expected to see this happen: It builds the documentation

Instead, this happened:

error: couldn't generate documentation: invalid template: invalid format: should have a newline on the last line

  = note: failed to create or modify "/home/neikos/projects/software-suite/target/doc/search-index.js"

error: could not document `unicode-ident`
warning: build failed, waiting for other jobs to finish...
error: could not document `smallvec`
error: could not document `thiserror`

Research direction

Reproduce the report by running cargo doc, interrupting it with Ctrl-C, and running it again. Start by examining the generated target/doc/search-index.js mentioned in the error and the reported rustdoc version; done means documentation generation succeeds on the second run without the invalid-template error.
