[PATCH 5/7] git-receive-pack.txt: wrap shell [script] listing in "----"

["Martin Ågren" <martin.agren@gmail.com>]

The indented lines in the example shell script listing are indented
differently by AsciiDoc and Asciidoctor.

Fix this by marking the example shell script as a code listing by
wrapping it in "----".  Because this gives us some extra indentation, we
can remove the one that we have been carrying explicitly. That is, drop
the first tab of indentation on each line. For consistency, make the
same change to the short example shell session further down.

With AsciiDoc, this results in identical rendering before and after this
commit. Asciidoctor now renders this the same as AsciiDoc does.
