Peter FinnandKyleBarton bda33ec436 vim: Fix space forward bug with non-ASCII characters at EOL (#27860)
Closes https://github.com/zed-industries/zed/issues/27619

Fixes issue with right wrapped movement when a multi-byte character is
at the end of the line. This is done by grabbing the last character on
the current row and using that characters size to calculate the
`max_column` variable, which is used to decide if the next right
movement should move down the line or not.

We did notice a bit of code that could be an issue that we wanted to
call out.
[Here](https://github.com/zed-industries/zed/blob/main/crates/editor/src/display_map.rs#L1070)
inside of `clip_at_line_end` it also does a saturating_sub(1), assuming
a single byte character. We didn't run into any issues due to this line
but felt like a similar bug. We can apply a similar fix if wanted to
pose the question first.

Test case: Moving to next line when eol is a multi-byte character

Release Notes:

the eol

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
