The default shortcut to open git difftool (ctrl+t) is not available on
the "Local Branches" window. It is available when selecting a commit
from a local branch, a remote branch, or a tag from the "Local Branches"
window.
This is inconsistent since branches or tags are also commits, the
shortcut should also work on them directly.
This commit remedies this inconsistency by allowing the use of the
shortcut directly on a branch or a tag. The shortcut works both in the
"standard" mode and the "diffing" mode.
By constructing an arg vector manually, we no longer need to quote arguments
Mandate that args must be passed when building a command
Now you need to provide an args array when building a command.
There are a handful of places where we need to deal with a string,
such as with user-defined custom commands, and for those we now require
that at the callsite they use str.ToArgv to do that. I don't want
to provide a method out of the box for it because I want to discourage its
use.
For some reason we were invoking a command through a shell when amending a
commit, and I don't believe we needed to do that as there was nothing user-
supplied about the command. So I've switched to using a regular command out-
side the shell there
This begins a big refactor of moving more code out of the Gui struct into contexts, controllers, and helpers. We also move some code into structs in the
gui package purely for the sake of better encapsulation
