Doc examples opts 4105

DOC: examples: shortened opts for all code_cmds Closes #4105

This accompanies previous few commits..
Where I mostly just changed the obvious options:
--input -> -i
--output -> -o
--dataset -> -d
--recursive -> -r

maybe a few others (?)

the ones that I deemed non-obvious can be seen using
Something like that below

bash-3.2$ pwd
/Users/andy/Projects/datalad
bash-3.2$ pyfiles=`ls *py`; for pf in $pyfiles; do  cat $pf | grep code_cmd -A 2 | grep " --"; done
bash-3.2$ pyfiles=`ls */*py`; for pf in $pyfiles; do  cat $pf | grep code_cmd -A 2 | grep " --"; done
bash-3.2$ pyfiles=`ls */*/*py`; for pf in $pyfiles; do  cat $pf | grep code_cmd -A 2 | grep " --"; done
             code_cmd="datalad drop <path/to/content> --nocheck"),
             --source='https://github.com/datalad-datasets/longnow-podcasts.git'"""),
             datalad install --get-data \\
