Reproduction steps

I can not reproduce this reliably, so this looks like a spurious error, probably introduced by weird behavior from clangfmt (and clangd?). This looks incredibly cursed, but may help figuring out some edge cases of ropey so I posted here.

  1. open file myexample.c
  2. run :format to execute clangfmt
  3. index out of bounds error from ropey with the following shell output:
[user@pc freetypeexample]$ hx myexample.c
thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Byte index out of bounds: byte index 1418, Rope/RopeSlice byte length 1416', $HOME/.cargo/registry/src/github.aaakk.us.kg-1ecc6299db9ec823/ropey-1.3.1/src/rope.rs:637:41
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Very old issue but I believe this might have been related to: #4047. Either way I guess we could close this given it's for a year and a half old version? cc @the-mikedavis

Yeah let's close this to clean up. If it resurfaces, we can make a new issue or reopen this one.

@dead10ck dead10ck closed this as not planned Won't fix, can't repro, duplicate, stale Dec 11, 2022
