/* If this bit is set, then ^ and $ are always anchors (outside bracket
expressions, of course).
If this bit is not set, then it depends:
- ^ is an anchor if it is at the beginning of a regular
- expression or after an open-group or an alternation operator;
- $ is an anchor if it is at the end of a regular expression, or
- before a close-group or an alternation operator.

This bit could be (re)combined with RE_CONTEXT_INDEP_OPS, because
POSIX draft 11.2 says that * etc. in leading positions is undefined.
