One typo spotted, and a suggestion for improving output.

OK - now a one line function!

I had a look at this and the line is getting too long with the extra
information.   How about splitting the line like this:

colon_printf(_("%s-%s and %s-%s are in conflict\n"),
	alpm_pkg_get_name(q->conflict->package1),
	alpm_pkg_get_version(q->conflict->package1),
	alpm_pkg_get_name(q->conflict->package2),
	alpm_pkg_get_version(q->conflict->package2));
q->remove = noyes(_("Remove %s?"),
	alpm_pkg_get_name(q->conflict->package2));
