But libstdc++/doc/html is the entry in the wildcard_prefixes list.
What I mean is using a sub-directory in the changelog:

  * doc/html/manual/*: Love is all you need.

The use case is for subsets of the testsuite. I've added
libstdc++-v3/testsuite to the wildcard_prefixes, which means I can now
do this:

 * testsuite/*: Update all 28_regex tests.

But I would like to do this:

 * testsuite/28_regex/*: Update all tests.

The concrete use case is:

* testsuite/20_util/specialized_algorithms/pstl/*: Add dg-timeout-factor.
* testsuite/25_algorithms/pstl/*: Likewise.
* testsuite/26_numerics/pstl/*: Likewise.
* testsuite/28_regex/*: Likewise.

I'm modifying four specific sub-directories, so I'd like to say that
in the changelog. Currently to allow that I'd have to add every
directory under libstdc++-v3/testsuite to the wildcard_prefixes (which
doesn't scale) or just be vague instead of saying which
sub-directories are affected:

* testsuite/*: Add dg-timeout-factor to most pstl and regex tests.
