Bug #2501: \c before a hex or octal encoded character is no longer allowed

Ruby 1.8 used to allow this:
  "\c\x33" #(0x33 is the ascii code for '3')
as meaning the same thing as this:
  "\c3"
However, it now (in ruby 1.9.1) causes a syntax error. Likewise with octal escape sequences. Is this an intentional change? It seems like an unnecessary restriction.

Tested in 1.9.1; I have no 1.9.2 handy to test with.
