[PATCH] git-gui: insert menu entries for added remotes before the "All" entry

[Tom Levy <tomlevy93@gmail.com>]

Hi,

git-gui has a bug in the way it adds menu entries for new remotes.

When a remote is added (using Remote > Add...), menu entries for the
new remote are currently added to the end of the "Fetch from" and
"Prune from" submenus.

However, those submenus normally have a special entry "All" at the
end. Adding the new entries at the end messes up the order, and also
causes the "All" entry to be added multiple times because
'update_all_remotes_menu_entry' re-adds an "All" entry if the last
entry is not "All".

The patch below inserts the new entries before the "All" entry.

I moved the logic for checking if the "All" entry exists into a new
procedure 'has_all_remotes_menu_entry'. Note that this changes the
first condition in 'update_all_remotes_menu_entry'; previously the
negation was subtly broken.

Regards,
Tom Levy

Subject: [PATCH] git-gui: insert menu entries for added remotes before the
 "All" entry

When a remote is added, the new fetch/prune menu entries need to be
inserted before the "All" entry (and its separator) rather than at the
end, so that "All" will remain the last option.
