Arguments escape not uniform

[faceair]

Describe the bug

After the crossplane parse, I expect all arguments to be unescaped.

https://github.com/nginxinc/crossplane/blob/v0.5.7/tests/test_parse.py#L946
Here, arg1 is escaped, but arg2 is unescaped, where the data format is not uniform. My program is confused when dealing with the arguments of the directive and doesn't know when it should be manually unescape.

Expected behavior

'args': ['#arg 1', '#arg 2']

I wrote a parser myself to solve this problem.
