2630 "CONFIGURATION FILE" section of <a href="git-config.html">git-config(1)</a>. By
2631 default, colors are shown only when enabled for log output
2632 (by <code>color.diff</code>, <code>color.ui</code>, or <code>--color</code>, and respecting
2633 the <code>auto</code> settings of the former if we are going to a
2634 terminal). <code>%C(auto,...)</code> is accepted as a historical
2635 synonym for the default (e.g., <code>%C(auto,red)</code>). Specifying
2636 <code>%C(always,...)</code> will show the colors even when color is
2637 not otherwise enabled (though consider just using
2638 <code>--color=always</code> to enable color for the whole output,
2639 including this format and anything else git might color).
2640 <code>auto</code> alone (i.e. <code>%C(auto)</code>) will turn on auto coloring
2641 on the next placeholders until the color is switched

3311 given multiple times trailer lines matching any of the keys are
3312 shown. This option automatically enables the <code>only</code> option so that

3315 <code>%(trailers:key=Reviewed-by)</code> shows trailer lines with key

3329 terminated with a line feed character. The string &lt;sep&gt; may contain
3330 the literal formatting codes described above. To use comma as
3331 separator one must use <code>%x2C</code> as it would otherwise be parsed as
3332 next option. E.g., <code>%(trailers:key=Ticket,separator=%x2C )</code>
3333 shows all trailer lines whose key is "Ticket" separated by a comma
3334 and a space.

3403 newline) appended, rather than a separator placed between entries.
3404 This means that the final entry of a single-line format will be properly
3405 terminated with a new line, just as the "oneline" format does.
3406 For example:</p></div>

3418 </div></div>
3419 <div class="paragraph"><p>In addition, any unrecognized string that has a <code>%</code> in it is interpreted
3420 as if it has <code>tformat:</code> in front of it. For example, these two are
3421 equivalent:</p></div>

3880 Chunk header format is modified to prevent people from
3881 accidentally feeding it to <code>patch -p1</code>. Combined diff format

3897 compares two or more files file1, file2,&#8230; with one file X, and
3898 shows how X differs from each of fileN. One column for each of

3900 different from it.</p></div>

3903 in the column N means that the line appears in the result,
3904 and fileN does not have that line (in other words, the line was
3905 added, from the point of view of that parent).</p></div>
3906 <div class="paragraph"><p>In the above example output, the function signature was changed
3907 from both files (hence two <code>-</code> removals from both file1 and
3908 file2, plus <code>++</code> to mean one line that was added does not appear
3909 in either file1 or file2). Also eight other lines are the same
3910 from file1 but do not appear in file2 (hence prefixed with <code>+</code>).</p></div>
3911 <div class="paragraph"><p>When shown by <code>git diff-tree -c</code>, it compares the parents of a

3914 two unresolved merge parents with the working tree file
3915 (i.e. file1 is stage 2 aka "our version", file2 is stage 3 aka
3916 "their version").</p></div>

3926 <div class="paragraph"><p>When showing a change that involves a rename or a copy, <code>--stat</code> output
