Subject: [PATCH] notify when new script version is available (#29)

- notify when new script version is available
- repair search for date
- print first variable assignment instead of end-of-file date (66a8ca8d7e)
- repair `sleep` calls
- add end-of-options delimiter to `read` (#30)
- upgrade, repair changelog generator (#31)
- match GNU `sed` debug formatting
- check connection with more widely accessible host
- check for update using globally-accessible URL
- generate brew bundle with VSCode extensions
- truncate `$IFS` only if modified
