Re: [Po4a-devel]Sgml.pm: Issue an error if nsgmls is missing

Here's a better version of this patch. The perl documentation says that when using open "cmd|" we can get the process exit code in '$?' after the close. So this is what this patch does. If everything went well nsgmls returns 0 and this is what we should get. If anything went wrong we will get a non-zero error code and print a message. I also removed the 'cat' to not have multiple child processes though I don't think this is strictly necessary. But it seems cleaner and should be ever so slightly more efficient too. Changelog: * lib/Locale/Po4a/Sgml.pm Francois Gouget <fgouget(a)codeweavers.com&gt; Check the nsgmls exit code and issue an error if it is non-zero. This lets us detect the case where nsgmls is missing.
