[PATCH 2/2] clear the heredoc list in case par_event() fails

[Kamil Dudka <kdudka@redhat.com>]

... in order to prevent SIGSEGV on the following input when running
in the interactive mode:

<<X;'
^C

^C

The console output looks like this:
kdudka% <<X;'
quote>
kdudka%
heredoc>
zsh: segmentation fault (core dumped)  zsh -f
