hello, > these tools by default use basic regexps (BRE).
Out of curiosity: To me, it's just a reason of retrocompat: no people dare breaking everything at some point. I really dislike the fact that it's confusing (for example: + must be protected but not *). But is there another good reason for BRE to be still alive? (perfomance, simplicity, or anything else).
