- Introduce WriteError variant in CatError enum to specifically handle stdout write failures - Add map_write_err helper to wrap io::Result into CatResult with WriteError - Update cat_files to catch WriteError early and report using localized message - Wrap write_all and flush calls in write_fast and write_lines with map_write_err - Add localized error messages for "write error" in en-US and fr-FR locales This improves error reporting for I/O issues like broken pipes during output.
…ite_nonprint_to_end Removed a trailing semicolon following the match arms in the `write_nonprint_to_end` function, which was likely causing a compiler warning or style issue in Rust. This ensures cleaner code without altering functionality.
- Adds a new test case to verify that `cat /dev/stdin` properly handles writing to a full device (/dev/full) and outputs the correct error message "No space left on device" without the raw errno code. This improves test coverage for error handling on Unix-like systems.
- Prevents spell-checker from flagging ENOSPC as a misspelling, as it's a valid errno constant (e.g., "No space left on device") used in the test code.

I did not know that we have our own error messages instead of extracting from OS. |

@mattsu2020 FYI, the "merge branch" just makes review slower ;) |
