Completion of error handling

[elfring]

Would you like to add more error handling for return values from functions like the following?

• fprintf ⇒ Pager::end
• fputs ⇒ html_perror

What use case do you have in mind where this would be important?

[elfring]

I suggest to avoid ignorance of return values a bit more.
Would you like to detect every error situation as early as possible?

[dspinellis]

I prefer to prioritize based on common sense.

Do you care if the desired file output succeeded?

[dspinellis]

You fail to understand that in this case output does not go to a file.

Would you like to clarify the failure probability for the mentioned HTML output a bit more?
