[PATCH 1/2] Documentation/git-show-branch: drop last use of {apostrophe}

[Todd Zullinger <tmz@pobox.com>]

The {apostrophe} was needed at the time of a521845800 ("Documentation:
remove stray backslash in show-branch discussion", 2010-08-20).  All
other uses of {apostrophe} were removed in 6cf378f0cb ("docs: stop using
asciidoc no-inline-literal", 2012-04-26).

Escape only the leading single-quote.  This renders properly in asciidoc
and asciidoctor.

Maybe it would be easier to change the example commit messages
and avoid having to nest single quotes within double quotes?  I
don't know if that's much preferable to escaping only the opening
single quote.

I went with the more minimal change to avoid having to rewrite
other bits of the example (and risk making them not match what
users would see if they ran similar commands).

This is another potential parsing bug in asciidoctor.  Of course,
distros will have versions of asciidoctor in place for some time
which have trouble parsing this doc.  Since it's not much work
for us to adjust the text to work around it, that seemed
reasonable.
