You can always (temporarily) remove your customizations from ~/Library/Application Support/TextMate/Bundles

From https://github.com/textmate/python.tmbundle/blob/textmate-1.x/Syntaxes/Python.tmLanguage

   <key>foldingStartMarker</key>
   <string>^\s*(def|class)\s+([.a-zA-Z0-9_ <]+)\s*(\((.*)\))?\s*:|\{\s*$|\(\s*$|\[\s*$|^\s*"""(?=.)(?!.*""")</string>
   <key>foldingStopMarker</key>
   <string>^\s*$|^\s*\}|^\s*\]|^\s*\)|^\s*"""\s*$</string>

You may want to clone the (1.x branch) of that bundle so that future changes are under version control.

Use alternations, i.e.: foldingStartMarker = 'foo|bar'. This will fold on either ‘foo’ or ‘bar’.

You can enable extended mode for regular expressions to have whitespace ignored and comment support, which can be used to make them more readable.

Look e.g. at the HTML folding patterns.
