Description of problem:

When choosing to display the component of a bug in a query list, that column
often gets truncated.

Version-Release number of selected component (if applicable):
2.18

How reproducible:
Easy

Steps to Reproduce:
1. Search for "system-config"
2. If not displayed, click on "Change Columns" to display the component column
  
Actual results:
Lots of "redhat-c" and "system-c" components which are not really distinguishable.

Expected results:
Complete name, e.g. by resizing the column appropriately or offering to display
the whole column instead of a truncated one (at the expense of having a
horizontal scroll bar)

Additional info:
Likewise for other columns, e.g. Product (lots of "Red Hat" products)
