Summary and Info:
The --help output of `pacman -Q` includes a rather ambiguous statement (imho). For '-l, --list', the help information is "list the contents of the queried package". In regards to a package manager, the "contents" of a package might be something like the metadata (such as information listed with -Qi) or even the metadata files associated with the package that are stored in the database tree.

Meanwhile, the manpage has a much clearer definition of the command:
"List all files owned by a given package. ..."

So while commands like --info, --check, and --owns have --help output that mentions 'file' or 'files', --list does not, despite it being closely related to files owned by a package.

I think it would be worthwhile to change the wording of the --help output for `pacman -Q` in regards to the --list option because a very common thing to do when searching for help (besides reading the manpage) is grep such output for the words users associate with such a command ('file' or 'files' would be useful here).

Steps to reproduce:
1. pacman -Qh | grep -i content
vs.
1. pacman -Qh | grep -i file
