Case where auto correction of multiline { } to do end block introduces a syntax error

[rousisk]

This snippet:

my_method :arg1, arg2: proc { 
  # assume a long proc that warrants the use of multiple lines
}, arg3: :another_value

is being auto corrected to:

my_method :arg1, arg2: proc do 
  # assume a long proc that warrants the use of multiple lines
end, arg3: :another_value

which raises a syntax error (due to the precedence differences between {} and do end).

Indeed. We should check for AST changes before doing such auto-corrections. @jonas054 Would you take care of this?

Sure.
