regex::sub_match::length()

| Milestone: | To Be Determined | Component: | regex |
| Version: | Boost 1.44.0 | Severity: | Problem |
| Keywords: | regex sub_match length | Cc: |
Description
code does not match documentation. if matched==false length() does not return 0, instead it results in an assertion of "string iterators incompatible" docs state:
static difference_type length(); Effects: returns the length of this matched sub-expression, or 0 if this sub-expression was not matched: matched ? distance(first, second) : 0).
Checked the source, code is broke.

this also affects the .str() method. if you call matchmissing.str() and there is no such named group, it fails with the same assert.
