Indentation error in generated Python code for a lengthy documentation line.

[xiangyan99]

If the doc is long and cannot be split into multiple lines, the generated Python code has an indentation issue. e.g. in
https://github.com/Azure/azure-rest-api-specs/blob/d0cb8714487b8b579eda933fd3435ce8d5a69a6e/specification/search/Azure.Search/models-service.tsp

I have docs like
"/subscriptions/12345678-1234-1234-1234-1234567890ab/resourceGroups/rg/providers/Microsoft.ManagedIdentity/userAssignedIdentities/myId"

The generated code misses the spaces in the beginning.
