Get Magit additions into Emacs

[tarsius]

Magit contains some features that should instead be implemented directly in Emacs. This list is not exhaustive, I intend to add to it as I run into more things.

• Ediff provides two commands for resolving conflicts with the help of some vcs. For each vcs and/or vcs interface some parts have to be implemented separately. The issues are in the common part: most importantly the user has to resolve all conflict, including those that the vcs already resolved successfully. Also see Can Magit be used as ediff-version-control-package?.

• Emacs provides the option server-window to allow users to customize what function should be used to show the buffer and optionally switch to the used window. But sometimes that isn't enough because a user or package wants to use different function for different files. The with-editor package (which was written for the benefit of Magit and was originally part of it) defines an additional option with-editor-server-window-alist and advices server-switch-buffer to respect that. Emacs should just provide such an option itself.

• Teach tabulated-list about :help-echo. See magit-repolist-columns: specify help-echo for narrow columns #3233.

• Fix auth-source bug. See magit/ghub@3ba8646. Done, will be fixed in Emacs 26.2 (emacs-mirror/emacs@5e42c34)

Fix auth-source bug. See magit/ghub@3ba8646.

This one is fixed in emacs-master now (specificallly, emacs-mirror/emacs@60ff810). Do you think it's worth backporting to 26.2?

I don't know the policy, but this is clearly a bug and the fix comes with tests and all. I think this should make it into the next release because the fixed issue is rather confusing.

[npostavs]

I've pushed it to emacs-26 (and updated the OP here).

I am busy improving magit instead (and already had to extend the "year" of magit to 15 months). Maybe next year...
