Subject: [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.
