I am little hesitant to do this, because I think people have scripted
minorly around the template format (at the very least, for syntax
highlighting). I think some people may have pre-written templates, as
well, though I guess your "If we do not see..." paragraph is meant to
address that. Though that brings some confusion itself, because now the
parsing rules for what is kept change if I delete that line.

Here's a patch series that at least improves the situation by turning
off the diff-stripping if we never put in a diff in the first place.
That way only people who actually _use_ "-v" will have to pay for it.
It has the fix I sent to Santi earlier, as well as some related
cleanups.

    1/5: define empty tree sha1 as a macro
    2/5: wt-status: refactor initial commit printing
    3/5: status: show "-v" diff even for initial commit
    4/5: commit: loosen pattern for matching "-v" diff
    5/5: commit: only strip diff from message in verbose mode
