Looks like a bug.  I find it suggestive that the length of the truncated
string is 12 characters - the same length as an 8+3 filename including the
period.

It gets even more interesting, however: the same code works as an -e
expression:

	$ ruby -ve '$0 = "My Application"; puts $0'
	ruby 1.8.1 (2003-12-05) [i686-linux]
	My Application

(Different quotes for ease of keeping the shell out; I verified that
 changing the quotes in t.rb to double didn't affect the beahvior)
