Bug 6212 – regex fails to make matches that include newline

import std.stdio; import std.regex; void main() { string str = "ABC\nDEF"; str = str.replace(regex("B(.*)E"), ""); writeln(str); } Expected Output: AF Actual Output: ABC DEF Note that the "m" attribute ("treat as multiple lines separated by newlines") was NOT used.

The '.' does not match the new line '\n'. This is by design.

Technically deep down std.regex there *is* an option to do that, namely REA.dotmatcheslf option. However it was never exposed in std.regex interface... So we definitely need to do one of two: expose "dot matches lf" option or kill all of it inside implementation to remove junk. Thoughts?
