Bug#948025: tint: infinite loop after Ctrl+D on level prompt

[Ricardo Mones]

Package: tint
Version: 0.05
Severity: normal
Tags: upstream

Dear Maintainer,

   * What led up to the situation?

When program is started without arguments it prompts for a starting level
and suggests a number between 1 and 9. If you do not enter a valid
number the prompt is printed again waiting for a valid input.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I entered Ctrl+D.

   * What was the outcome of this action?

The prompt started to be rinted continuously, without waiting.
Fortunately pressing Ctrl+C aborted the program.

   * What outcome did you expect instead?

The prompt to be printed once and waiting for input.
