           Milestone:  5.2      |  Component:  core libraries
             Version:  5.1.0    |   Keywords:  irregex
Estimated difficulty:  medium   |
--------------------------------+----------------------------
 Reported by Petruchio on IRC:

 ```
 (irregex-replace/all (irregex 'bol) "Line1\nLine2" "*")
 =>
 "ine1\n*Line2"
 ```

 Expected output is `"*Line1\n*Line2"`.  If you use `bos` instead of `bol`
 the first character gets "eaten" as well.
