handle ^ and $ in BRE subexpression start and end as anchors
In BRE, ^ is an anchor at the beginning of an expression, optionally it may be an anchor at the beginning of a subexpression and must be treated as a literal otherwise. Previously musl treated ^ in subexpressions as literal, but at least glibc and gnu sed treats it as an anchor and that's the more useful behaviour: it can always be escaped to get back the literal meaning. Same for $ at the end of a subexpression. Portable BRE should not rely on this, but there are sed commands in build scripts which do. This changes the meaning of the BREs: \(^a\) \(a\|^b\) \(a$\) \(a$\|b\)
