I have this in my man page (yum 3.0.3-1.fc6):
All the list options mentioned above take file-glob-syntax wildcards or package
names as arguments, for example yum list available ’foo*’ will list all
available packages that match ’foo*’. (The single quotes will keep your shell
from expanding the globs.
Notice that the parenthesis is unclosed.
fixed in upstream cvs. Thank you.
