Sven Panne afe627e7af Avoid a -Warray-bounds false positive in GCC 13. (#1639) ...

The exact circumstances when this false positive is triggered are quite
tricky to reproduce, but it happened reproducibly with g++ 13.1 and 13.2 in
a close-source SW I'm working on.  The fix even improves performance by a
very tiny bit: There is no need to copy the std::smatch, having a const
reference is enough.

Just as a side note: -Warray-bounds seems to cause trouble in other
projects, too, so e.g. the Linux kernel has disabled since June 2022.
