The info proc commands accept a pid, which allows you to refer to any
process, not only those debugged by GDB.  Other info proc commands use
use the generic form "of the process"

  info proc cmdline -- List command line arguments of the process

I think that's sufficient, especially that users are likely to see it
in the context of "help info proc", which describes what argument you
can pass:

(gdb) help info proc
Show /proc process information about any running process.
Specify any process id, or use the program being debugged by default.

List of info proc subcommands:

info proc all -- List all available /proc info
info proc cmdline -- List command line arguments of the process
info proc cwd -- List current working directory of the process
info proc exe -- List absolute filename for executable of the process
info proc mappings -- List of mapped memory regions
info proc stat -- List process info from /proc/PID/stat
info proc status -- List process info from /proc/PID/status
