Subject: [PATCH 1/6] Use strictly compliant POSIX BREs in build

- '\+' is not defined by the POSIX standard for basic regular
  expressions [*] and is matched literally by many grep(1) and sed(1)
  implementations. Replace with the equivalent '\{1,\}'. In sed(1)
  scripts that already use "," as a delimiter, change the delimiter to
  avoid conflicts.
- '\"' is not defined by the POSIX standard. Replace with '"'.

These changes are necessary to build on macOS.
