Dear Maintainer,
When executing:
$ Var='Example1 $(Example2)'
$ echo "${Var#*'$('}"

I see an error:
bash: command substitution: line 6: unexpected EOF while looking for 
matching `''

instend of the expected result of cutting off part of the text.
dash and busybox ash work as excepted:
$ echo "${Var#*'$('}"
Example2)
