Perhaps enhance the commit message to explain the nature of the bug
itself. It is not at all obvious from reading the above or from
looking at the diff itself what the actual problem is that the patch
is fixing. (And it wasn't even immediately obvious by looking at the
commit message of ec2c84d in the dash repository.) To help readers of
this patch avoid re-introducing this problem or diagnose such a
failure, it might be a good idea to give an example of the syntax
which trips up old dash (i.e. a here-doc followed immediately by a
{...} expression) and the actual error message 'Syntax error: "}"
unexpected'.

Thanks.
