Description of problem:

The output of 'yum list' is not pipeline-friendly.

For example, depending on what is installed and how long the package names are, one may need to "unwrap" lines like this, to get a list of installed packages from either epel or ius:

yum list installed|awk '$3 == "@epel" ||  $3 == "@ius" {print} NF == 1 {line=$0}  $2 == "@epel" || $2 == "@ius" {print line,$0}'

The above line-joining becomes necessary because some of output is formatted like this:

package-name-on-one-line
                       version-number-and   @reponame

instead of this:

package-name-on-same-line-as  version-number-and   @reponame

How reproducible:

run "yum list installed"

Steps to Reproduce:
1.  Install packages with long packagenames
2.  run "yum list installed"
3.  Note how yum wraps the information about a package onto the next line

Actual results:

package-name-on-one-line
                       version-number-and   @reponame

Expected results:

package-name-on-same-line-as  version-number-and   @reponame

Additional info:

Someone had to actually add code to get the output to wrap onto a second line, so this should be easy enough to find and remove.  It is much more important that the program be pipeline-friendly than to have it look pretty on screen.
