asking a question again if given an invalid input instead of assuming
what the user wants. /etc is not the place to make assumptions when
given invalid input.
Reformat some of the more convoluted code into seperate functions instead
of being inline using tabs instead of space indents.
Allow the user to view merged files they created with sdiff.
Allow the user to redisplay the diff between the installed file and
the new file again.
Time wasted waiting for review: 1 month 2 weeks
