Here's an example.  I have a runtest.rb library as part of Rake that 
handles the details of running tests (and managing the -I part!).  If 
rake is installed as a non-gem, the command line to run the test is

   ruby -Ilib -rrake/runtest \
     -e 'Rake.run_tests("test/test*.rb", true)'

If rake is installed as a gem, then it needs to be ...

   ruby -Ilib -e 'require "rubygems"; require_gem "rake"' \
     -e 'require "rake/runtest"' \
     -e 'Rake.run_tests("test/test*.rb", true)'

I won't even mention the logic required to *detect* if rake is installed 
as a gem or not.

If Simon's patch is part of gem (and we assume gem is installed), then 
all I need for either case is ...

   ruby -rubygems -rrake/runtest \
     -e 'Rake.run_tests("test/test*.rb", true)'

And no detection logic is required!

Simon's patch really simplifies things for me (in this case).
