--------------------------------------------------------------
Attached a patch and two test cases. This patch changes the REPLACE_MULTI
semantic:
- no chaining of replacement rule, all are applied now in one go, rule "a" ->
"b" and "b" -> "c" on "a b" will result in "b c" and not "c c", like before
- keys in the replacement map are treated as plain string, and not regex: "|"
-> "x" will replace all "|" to "x" in input
[~rohini] could you please have a look at my patch?

> REPLACE_MULTI should compile Pattern once and reuse it
