From e2df6dcefedb2cc6b1d0559154a871587ed2748d Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/6] [PARSER] Remove backslash before } in double-quotes in
variable
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.
