1-letter shortcut for --reobtain-data in datalad-update

[mlell]

What is the problem?

I have an analysis that is grouped into multiple datalad datasets, where "downstream" datasets use the results from "upstream" analyses. If I am fixing things in the upstream datasets and re-run the downstream analyses, I find myself typing frequently

cd input/upstream1
datalad update --how=ff-only --reobtain-data

It would be so much nicer if I was just

datalad update --how=ff-only -o

That's ~1/3 less command size

I know, its not a large problem, I can write helper scripts, etc., but I frequently find this papercut so I figured I will just report it. If you do not like it, I write my alias, no problem

What steps will reproduce the problem?

I don't mind but it should not be -o since that is very commonly for --output even if not in datalad context. So should be something else, but -r, -R and -d are taken.... could be -D I guess or -g to be reminiscent of --get-data of install.

Longer shot, we could introduce a convention for abbreviating based on leading letters, such as --r-d for --reobtain-data and --f-a for --fetch-all
