   Can you be more precise? The "usage" function returns no value and the value returned by "parse_sed_like_string" is already tested.

   I suggest to avoid ignorance of return values a bit more.
   How do you think about to care also if a file output or a string copy really succeeded?

   Looks to me as this issue was resolved on same day - but the issue was not closed.

   The return value for strdup are handled now with the changes in 768f82b
   And ignoring the return value of *printf functions is usually not considered that a relevant issue - at least not, when this is done during output of help messages to stdout.

   💭 Would it matter if output redirection can occasionally fail?
