config: register the 'devel.bundle2.debug' config
Existing explicit default are dropped now that the default is centralised.
config: register the 'devel.all-warnings' config
Let us start registering the existing option. I'm starting with the 'devel'
section because it is full of useful things that are poorly documented. So
registering these will more than other section.
rebase: always pass destination as revnum to _handleskippingobsolete()
We were passing it as a revision number in one place and as a context
in another. It worked because the only use was in "repo[dest].rev()",
but it was confusing. By always passing a revision number, we can also
remove that unnecessary lookup.
patch: remove unused fsbackend._join()
The function lost its last caller in
2a095d3442e0 (patch: replace
functions in fsbackend to use vfs, 2014-06-05) when the callers
started relying on the opener to do the join.
patch: add close() to abstractbackend
patchbackend() seems to call it on an arbitrary backend, so it seems
to be part of the API. Since all subclasses do something in their
close() methods, I decided to let this one raise an exception rather
than just pass.
