Right now the documentation describes the syntax as git sees the
parameters. This is agnostic of the shell or other UI with their
different quoting rules.  For example users of fish must quote
`rev@{2}`. A GUI might require no quoting at all. In that case `:/"fix
nasty bugs"` would be given to git verbatim and hence not find the revision.

Also: Other examples like `HEAD@{5 minutes ago}` need the same quoting.

So my suggestion is to not use quoting in the examples and provide only
a hint in the text. Example:

 <rev>{caret}{/<text>}', e.g. 'HEAD^{/fix nasty bug}'::
    A suffix '{caret}' to a revision parameter, followed by a brace
    pair that contains a text led by a slash,
    is the same as the ':/fix nasty bug' syntax below except that
    it returns the youngest matching commit which is reachable from
    the '<rev>' before '{caret}'.
+   Depending on the given text the shell's word splitting rules
+   might require additional quoting.
