Description:
When a package fails to install with 'makepkg -i' the return status is zero ($? variable).
For example, in case of package conflict or dependency breaking.

This does not reflect that the command failed to do what is being requested (build _and_ install).

Since the return status is zero, a script cannot really on checking for 'makepkg -i' return status to test if a package was built _and_ correctly installed.

Changing this a non-zero return status would better reflect what happened and would allow a script to test/address this situation.


Additional info:
* package version(s): makepkg (pacman) 5.0.1


Steps to reproduce:
$ makepkg -i # using any package that causes a package conflict or dependency breaking
$ printf '%s\n' "$?" # result is 0
