Meaning of blankCompOpt is not documented

[raxod502]

The documentation for CompOption details two different values for each field, one for defaultCompOpt and one for blankCompOpt. However, neither of these variables are documented. I assume that defaultCompOpt is used if you use one of the convenience functions to construct a regex from a string (although #11 makes me unsure of this), but I cannot see where blankCompOpt is used even in the code. Why are there two variables?

They are part of the regex-base package, see, e.g. https://hackage.haskell.org/package/regex-base-0.94.0.2/docs/Text-Regex-Base-RegexLike.html#v:blankCompOpt.
