Snippet syntax issue when converting from TextMate bundle

[KazroFox]

I was trying to convert the restructuredText tmbundle into an atom package, and for the most part it works properly, but the snippet syntax it creates from the tmbundle doesn't work.

apm init --package ~/.atom/packages/language-rst --convert https://github.com/textmate/restructuredtext.tmbundle

In TextMate when you type sec and auto complete, this happens:

(If you can't see the image, it inserts text and as you type it dynamically resizes the line below it so the section title remains in proper syntax)

In atom, doing the same process results in

subsection name
${1/(.)|\s/(?1:=:=)/g}

being inserted into the editor.

Unfortunately, I'm not familiar with the syntax that the atom snippets use, so I don't know how to fix this issue. Even if this isn't possible to be handled in atom, there should probably be some sort of case to handle these snippets.

Here's the contents of the snippets/language-rst.cson that apm outputs:

'.text.restructuredtext':
  'image':
    'prefix': 'image'
    'body': '.. image:: ${1:path}\n$0'
  'link':
    'prefix': 'link'
    'body': '\n\\`${1:Title}<${2:http://link}>\\`_'
  'section 1':
    'prefix': 'sec'
    'body': '${1:subsection name}\n${1/(.)|\\s/(?1:=:=)/g}\n$0'
  'section 2':
    'prefix': 'subs'
    'body': '${1:subsection name}\n${1/(.)|\\s/(?1:*:*)/g}\n$0'
  'section 3':
    'prefix': 'sss'
    'body': '${1:subsection name}\n${1/(.)|\\s/(?1:-:-)/g}\n$0'
