Hi!

1. Open an empty Ruby source code, say "tmp.rb".
2. Type the following:
#!/usr/bin/ruby
base = ?a.ord - 1
On hitting the return key at the end of the second line, the cursor
moves below "a", not to the top of the third line. The indentation
state seems to be confused. I did this test with "emacs -q" .
Thanks for the report. I'd like to fix it sometime, but it's not a big
priority, considering this syntax is usually discouraged:

?a is a valid Ruby syntax for string literal. After writing this, I learned
that "a".ord is equivalent (I think)
Yes, in Ruby 1.9 and newer, it's a full equivalent.
