Re: [PATCH] Move all dashed form git commands to libexecdir

Support builtin aliases

Builtin aliases are "default" alias values that can be
overridden by user-configured aliases.

For example, the first such alias is "view", an alias for
gitk. A user with no further configuration can run
"git view" to use gitk. However, they can also set the
config option "alias.view" to "!tig" to run tig.
