BASE is: 4ad894096c4100a8a3813b24cd47d51ac8d50cbd
Referring to #1296 this fix the 920440 regex to \.[^\.]+$ preventing to make it match something like .com.sql instead of .sql.

You don't need to escape the period inside a character class. Otherwise LGTM.

You probably want to rebase it to exclude all the other changes/commits too.

fgsch I think I've done with rebase. Could you check if it's ok?
