grep: warn on censored revisions instead of erroring out
We need most of the grep logic to go through in case we encounter a
censored revision, so we just return a None body for a censored node,
and we stop just short of trying to record matches with the contents
of that censored body. The other parts such as recording that the
censored file has been considered at this revision needs to go into
the proper dicts.
I have also gotten weary of all the abbreviations, so while I did a
small refactor to move the file-data-getting operation into a common
function, I also expanded the abbreviations of the relevant variables
within this little function. Hopefully some day this helps someone
figure out what all the abbreviations mean.
Although the censoring docs currently state that some commands error
out or are ignored depending on the `censor.policy` config, I cannot
see a benefit for grep to ever stop dead in its tracks when a censored
revision is encountered. I will also amend the docs to indicate that
some commands, such as grep, unconditionally ignore censored
revisions.
