[Yum] ok, what i think all the "yum list" variations do

[Robert P. J. Day]

  (don't worry -- once i get all this cleared up, i'll get
distracted by something else and move to another project. :-)

  given the following terminology for packages:

  available:  exists somewhere in the repos
  new:  a package for which there is *no* earlier version installed
  newer: a package for which there *is* an earlier version installed

i think it works like this:

$ yum list
	list all new and newer available packages

$ yum list available
	list all new available packages

$ yum list updates
	list all newer available packages

$ yum list "glob"
	list all new and newer available packages matching "glob" PLUS
	list all installed packages matching "glob" (weird, this 2nd part)

$ yum list installed
	list all installed packages

$ yum list installed "glob"
	same as "yum list installed" (despite suggestion in man page,
 	"glob" appears to be ignored)

  is all that about right?  some of it is definitely non-intuitive, 
and it's odd that some of the variations take a "glob" and some don't,
even when they have similar functionality.
