 961         The option core.warnAmbiguousRefs is used to select the strict

 963         slash-separated path components from the front (back) of the refname

1080         %(align:&#8230;) and %(end). The "align:" is followed by
1081         <code>width=&lt;width&gt;</code> and <code>position=&lt;position&gt;</code> in any order
1082         separated by a comma, where the <code>&lt;position&gt;</code> is either left,
1083         right or middle, default being left and <code>&lt;width&gt;</code> is the total
1084         length of the content with alignment. For brevity, the
1085         "width=" and/or "position=" prefixes may be omitted, and bare
1086         &lt;width&gt; and &lt;position&gt; used instead.  For instance,
1087         <code>%(align:&lt;width&gt;,&lt;position&gt;)</code>. If the contents length is more
1088         than the width then no alignment is performed. If used with
1089         <code>--quote</code> everything in between %(align:&#8230;) and %(end) is
1090         quoted, but if nested then only the topmost level performs
