When this function is declared const or pure, clang at -O1 or higher optimizes
away the call to mu_str_size_s() inside mu_str_size(), so that it ignores its
argument and returns whatever is in mu_str_size_s()'s static buffer.
Found when test-mu-str failed while testing an update of mu in OpenBSD's ports tree.
We were verifying signatures when this was not needed; it seems that
gpgme is a bit slow (?), and on some people's machine the extra
verification made opening messages slow (with the non-gnus view esp.)
Today when we query a find cmd with the `--threads` option, all the
childs of each thread are sorted according to their leader based on
the sortfield.
This patch change the way of how the childs of a thread are sorted.
The threads are still sorted according to their leader but all the
childs of each thread are now sorted based on the sortfield only.
Here is an example of what happened with the previous sorting:
Example with random kernel thread sorted by date:
