Bug #628: Assigning to $0 truncates value
http://redmine.ruby-lang.org/issues/show/628

Author: Mike Furr
Status: Open, Priority: Normal

Consider the code:
  $0 = "abcdefghijklmnopqrstuvwxyz"
  puts $0

If I save this in "test.rb" and then invoke: "ruby test.rb", I get:
abcdefghijk

More interestingly is that the level of truncation seems tied to the length of the command line.  For instance, running "ruby -r yaml test.rb" outputs:
abcdefghijklmnopq

I'm running 1.8.7p72 (and this seems to be present in earlier versions, such as 1.8.5).
