Subject: [PATCH] replace_regex: remove bash word boundary when detecting

 gnused

Bash linked against C libraries other than GLibc may not support GNU

extensions of POSIX Extended Regular Regex. For example,

> re='\bx'; [[ 'x' =~ $re ]] && echo "1"

does not output the same result on Linux/GLibc and macOS.
