title: Use different prefix for const and non-const private members in editorconfig
body: <p>I want to use m_ for non-const private members and c_ for const ones. However, editorconfig doesn't allow me to specify a rule for non-const members only as far as I can see. The following doesn't work, regardless of the order of specification of private members in general or const ones:</p>
  
  <pre><code># Prefix private/protected fields with m_
  dotnet_naming_rule.prefix_private_members.symbols               = private_fields
  dotnet_naming_symbols.private_fields.applicable_kinds           = field
  dotnet_naming_symbols.private_fields.applicable_accessibilities = private;protected;protected_internal
  
  dotnet_naming_rule.prefix_private_members.style                 = private_prefix_style
  dotnet_naming_style.private_prefix_style.capitalization         = camel_case
  dotnet_naming_style.private_prefix_style.required_prefix        = m_
  
  dotnet_naming_rule.prefix_private_members.severity              = warning
  
  # Prefix private/protected const fields with c_
  dotnet_naming_rule.prefix_const_members.symbols                 = const_fields
  dotnet_naming_symbols.const_fields.applicable_kinds             = field
  dotnet_naming_symbols.const_fields.applicable_accessibilities   = private;protected;protected_internal
  dotnet_naming_symbols.const_fields.required_modifiers           = const
  
  dotnet_naming_rule.prefix_const_members.style                   = const_prefix_style
  dotnet_naming_style.const_prefix_style.capitalization           = camel_case
  dotnet_naming_style.const_prefix_style.required_prefix          = c_
  
  dotnet_naming_rule.prefix_const_members.severity                = warning
  </code></pre>
  
  <p>What do I do? I also tried using Pascal case instead of c_ to distinguish const, but the conflict still occurs since the camel_case for fields in general conflicts with that.</p>
