config: drop debug messages saying where config was read from
`hg config --debug` includes lines like this:
set config by: $EDITOR
but also lines like this:
$EDITOR: ui.editor=emacs -nw
The `set config by` messages don't seem to provide much additional
information over what we get from the `$EDITOR:`-type message. I could
imagine wanting to see which values got overriden by a later entry,
but that information is already not present. So let's just remove the
first type of output. My next patch would otherwise amplify the
redundant output (there would be one `set config by` for each line in
`mergetools.rc`).
