| Subject: | Regex error in case-insensitive mode |
If an item in the list contains the string "(+",
e.g. "Apples (+Bananas)" and -ignorecase is set to 1
a regex error occurs (quantifier follows nothing in regex)
because the text is evaluated as a regex.
The text is not correctly replaced by the item in the list.
I would suggest changing line 217 (in subroutine "check_choice_case"):
< if ($text =~ m/^$choice$/i && ($text ne $choice)) {
Show quoted text
> if ($text =~ m/^\Q$choice\E$/i && ($text ne $choice)) {
This would quotes all regex meta-characters in $choice
