Details

Summary and Info:

I'm not sure if this is a bug (if not, maybe the man page could mention this).
When attempting to print the list of targets for a --remove operation, if a HoldPkg is one of those targets, the list will never be printed. Instead ":: HoldPkg was found in target list. Do you want to continue? [y/N] " will be printed and pacman will exit immediately with error code 1.

Steps to Reproduce:

pacman -Rcp pacman
This task depends upon

What would you suggest as an alternative? Note that the current implementation is *accurate*, as no packages will be removed without user intervention to decide the fate of the HoldPkg.

Since the behaviour is accurate:
Interaction is impossible, so I think "Do you want to continue?" is a strange message to print. Since the command is likely to have its stdout captured and treated as a package list, it would probably make more sense if the message appeared on stderr.

Ah, didn't catch that part. Seems to be due to this:

https://projects.archlinux.org/pacman.git/tree/src/pacman/util.c#n1384

Which dates back to 2008... The same behavior exists in multiselect_question. Offhand, I'm not sure why we couldn't *always* dump this to stderr.
