Current evaluation

craft-cli bug: a permanent multi-line progress message only clears the first line of a previous temporary progress, leaving residual text. A maintainer diagnosed the printer path and opened fix PR #445 (open, pending review); bug still present in main.

Suggested action: keep open

Reason: A maintainer (gcomneno) triaged this, diagnosed the root cause in the printer's terminal output path, and opened fix PR #445 which is still open and pending review. The bug is confirmed reproducible with a clear reproducer and is not yet fixed in main (no matching commits found), so the issue remains valid and should stay open until the PR lands.

Issue body

### Bug Description I assumed it was possible to pass multi-line strings to `emit.progress`. At least, craft-application does it. However, the first line doesn't overwrite the existing progress line if it was longer. ### To Reproduce ```python from craft_cli import EmitterMode, emit emit.init(EmitterMode.BRIEF, appname="testcraft", greeting="Greeting") emit.progress("foo foo foo") emit.progress("bar\nbar", permanent=True) ``` Expected output: ``` bar bar ``` Actual output: ``` bar foo foo bar ``` ### part yaml ```shell ``` ### Relevant log output ```shell 2025-08-11 15:02:50.183 Greeting 2025-08-11 15:02:50.183 foo foo foo 2025-08-11 15:02:50.183 bar bar ```
