[PATCH] [PARSER] Remove backslash before } in double-quotes in variable

[Jilles Tjoelker]

The backslash prevents the closing brace from terminating the
substitution, therefore it should be removed.

FreeBSD sh test expansion/plus-minus2.0 starts working, no other tests
are affected.

Example:
  printf "%s\n" ${$+\}} ${$+"\}"} "${$+\}}"
should print } three times, without backslashes.
