Thanks for the tip. My LANG is pl_PL.UTF-8. Indeed, prefixing the "sort"
invocation in question with LANG=C does solve the problem. I don't feel
competent enough to say whether this is the correct place for the fix,
or if the fix should be made elsewhere. Another option is that it is the
"sort" itself that should be fixed (or the locale, or both).

Would you be able (as the author of the patch in question) to check if
there are other locales which cause the problem?

Thanks,

Andrzej
