 791         Instead of stopping at the first failed merge, do all of them
 792         in one shot - continue with merging even when previous merges
 793         returned errors, and only return the error code after all the
 794         merges.

 802         Do not complain about a failed merge program (a merge program
 803         failure usually indicates conflicts during the merge). This is for
 804         porcelains which might want to emit custom messages.

 807 </dl></div>
 808 <div class="paragraph"><p>If <em>git merge-index</em> is called with multiple &lt;file&gt;s (or -a) then it
 809 processes them in turn only stopping if merge returns a non-zero exit
 810 code.</p></div>
 811 <div class="paragraph"><p>Typically this is run with a script calling Git&#8217;s imitation of
 812 the <em>merge</em> command from the RCS package.</p></div>
 813 <div class="paragraph"><p>A sample script called <em>git merge-one-file</em> is included in the
 814 distribution.</p></div>
 815 <div class="paragraph"><p>ALERT ALERT ALERT! The Git "merge object order" is different from the
 816 RCS <em>merge</em> program merge object order. In the above ordering, the
 817 original is first. But the argument order to the 3-way merge program
 818 <em>merge</em> is to have the original in the middle. Don&#8217;t ask me why.</p></div>

 820 <div class="listingblock">
 821 <div class="content">
 822 <pre><code>torvalds@ppc970:~/merge-test&gt; git merge-index cat MM
 823 This is MM from the original tree.              # original
 824 This is modified MM in the branch A.            # merge1
 825 This is modified MM in the branch B.            # merge2
 826 This is modified MM in the branch B.            # current contents</code></pre>

 829 <div class="listingblock">
 830 <div class="content">
 831 <pre><code>torvalds@ppc970:~/merge-test&gt; git merge-index cat AA MM
 832 cat: : No such file or directory
 833 This is added AA in the branch A.
 834 This is added AA in the branch B.
 835 This is added AA in the branch B.
 836 fatal: merge program failed</code></pre>
 837 </div></div>
 838 <div class="paragraph"><p>where the latter example shows how <em>git merge-index</em> will stop trying to
 839 merge once anything has returned an error (i.e., <code>cat</code> returned an error
 840 for the AA file, because it didn&#8217;t exist in the original, and thus
 841 <em>git merge-index</em> didn&#8217;t even try to merge the MM thing).</p></div>
