Bugfix: Fix rare crash in command output
Some commands could in rare cases crash when trying to print status messages
and request retries at the same time. This resulted in an error like the following:
```
panic: runtime error: slice bounds out of range [468:156]
[...]
github.com/restic/restic/internal/ui/termstatus.(*lineWriter).Write(...)
/restic/internal/ui/termstatus/stdio_wrapper.go:36 +0x136
```
This has been fixed.
