sslutil: check for ui.insecureconnections in sslkwargs
The end result of this function is the same. We now have a more
explicit return branch.
We still keep the old code looking at web.cacerts=! a few lines
below because we're still setting web.cacerts=! and need to react
to the variable. This will be removed in an upcoming patch.
$ hg init
$ echo This is file a1 > a
$ hg add a
$ hg commit -m "commit #0"
$ ls
a
$ echo This is file b1 > b
$ hg add b
$ hg commit -m "commit #1"
$ hg co 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
B should disappear
$ ls
a
