Michael S. Tsirkin ccba805681 doc: don't claim that cherry calls patch-id
The id is already different for binary files.  The hash used is an
implementation detail, so let's just document how diffs are compared.

git-cherry(1)
=============
NAME
----
git-cherry - Find commits not merged upstream
SYNOPSIS
--------
[verse]
'git cherry' [-v] [<upstream> [<head> [<limit>]]]
DESCRIPTION
-----------
The changeset (or "diff") of each commit between the fork-point and <head>
is compared against each commit between the fork-point and <upstream>.
The diffs are compared after removing any whitespace and line numbers.
Every commit that doesn't exist in the <upstream> branch
has its id (sha1) reported, prefixed by a symbol. The ones that have
equivalent change already
in the <upstream> branch are prefixed with a minus (-) sign, and those
that only exist in the <head> branch are prefixed with a plus (+) symbol:
__*__*__*__*__> <upstream>
/
fork-point
\__+__+__-__+__+__-__+__> <head>
If a <limit> has been given then the commits along the <head> branch up
to and including <limit> are not reported:
__*__*__*__*__> <upstream>
/
fork-point
\__*__*__<limit>__-__+__> <head>
Because 'git cherry' compares the changeset rather than the commit id
(sha1), you can use 'git cherry' to find out if a commit you made locally
has been applied <upstream> under a different commit id. For example,
this will happen if you're feeding patches <upstream> via email rather
than pushing or pulling commits directly.
