Verified that both procexp and process hacker tools do not have this issue.
I took a look at process_info.c and didn't notice anything weird so I 
have no clue on where I might look.

It's because you call CommandLineToArgvW, and its purpose is to parse 
the command line string to remove quotes and backslashes...

Hints on what to use as replacement?

We're returning an array of process arguments, not a string...  I 
would think this is expected behavior. This is similar to what you 
get from sys.argv where the arguments are already parsed, which is 
what CommandLineToArgvW is supposed to do, and we return the 
corresponding array of strings as a Python list.

Verified that the same thing happens on Linux and BSD/OSX.
Thinking back I guess it's ok to return strings without quotation 
marks as well, also because that's what you would pass to 
subprocess.Popen in case you want to attempt to restart the process, for example.
I'm going to close this out and modify the test case.
