Whats the easiest command to show the parent commit of a given commit id
(the closest analogy I can think of)? I tried:

 git-show 486a974a --pretty="format:%P"

 * Have rev before option, like "git show --pretty=... 486a974"

 * Use -s to squelch diff output.

You should check how the %P format shows parents for a merge and
decide which parent you would want to follow.
