Do you mean something like "should a difference in regexp handling between
LibreOffice and egrep be considered a bug"? No, we use a different regexp
library - ICU (and generally, there are lots of regexp implementations, with
different behaviours [1] [2]); the only thing that matters is that LibreOffice
works as described in its own help.
