Last character of right prompt truncated in ghostty

[Crocmagnon]

Describe the bug

The last character of the right prompt is truncated in ghostty. This only affects the right prompt and not the terminal output (see screenshot: "hello" is correctly printed).

Steps to reproduce

1. Open Ghostty
2. Trigger anything on the right prompt (python venv, go version, duration, signal, ...)

ORIGINAL COMMENT

This happens also in other terminals; this is a screenshot from Windows Terminal open in a WSL shell:

From the linked thread on Ghostty, it seems like the problem should be fixed in Fish or Tide, since it could manifest in multiple terminals depending on how they handle writing a character in the last column: https://github.com/ghostty-org/ghostty/issues/884#issuecomment-1813185031
