Fallback values used in a formatter without spaces do not work as expected

[ezekg]

For example,

cat /etc/apache2/sites-available/*.conf | xo '/\*:443.*?ServerName\s(www\.)?([-.0-9A-Za-z]+)/$1:?www.$2/mis'

stops on the . after www, so sites that contain www. in the name are output as www..site-name.com. To fix this, we should introduce optionally wrapping fallback values within parenthesis, as well as support for escaping those parenthesis in the case that they are actually needed in the formatter.

Oversight on my part. It is working correctly. If we handle allowing periods inside of fallback values then it will mess up formatting sentences, which is what xo is often used for, when the value needs to end with a period. Corrected command would be:

cat /etc/apache2/sites-available/*.conf | xo '/\*:443.*?ServerName\s(www)?\.?([-.0-9A-Za-z]+)/$1?:www.$2/mis'
