context: remove seemingly impossible code branch
I'm not a Python expert, but I can't think of a way that the following
branch can ever be hit:
def _changeid(self):
if r'_changeid' in self.__dict__:
return self._changeid
It seems to me that if that condition is true, then this function
would not have been called. The only exception I can think of is if a
reference to the function had been stored beforehand, something like this:
c = fctx.__dict__['_changeid']
fctx._changeid
c()
But that seems like very unlikely code to exist.
The condition was added in 921b64e1f7b9 (filecontext: use 'is not
None' to check for filelog existence, 2013-05-01) as a "bonus" change
(in addition to what the patch was actually about)
