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.

Subject: [PATCH] sed_version: remove word boundary assertions

Word boundary assertions (\b) are GNU regex extensions that may fail

on systems using non-glibc C libraries (e.g., musl, macOS).

This was previously fixed in replace_regex() via NixOS/nixpkgs#388412,

which was subsequently upstreamed in amber-lang/amber#686.

Changes in amber-lang/amber#717 reintroduced the same portability issue.
