 Description   

In a multi-source replications I have many connection_name's with a dot in the name.
For example public.repl

Now I what to set a replicate-filter like replicate_wild_do_table.
While I have no problem creating the filter using the client and setting 

set default_master_connection = 'public.repl'

I cannot set it using .cnf file.
So I have to manually set it on each restart.

I've tried using: 

public_repl.replicate_wild_do_table
 
public-repl.replicate_wild_do_table

and even 

public@002erepl.replicate_wild_do_table

following the binary files name convention.

I'll leave it to Elkin to decide whether it's worth fixing or it should be moved to documentation to be added to the limitation section of multi-source replication.

To the patch comments and commit message, consider my notes.

Btw this means that all but the last '.' are part of the name. The last period is a struct connector.
 
Maybe it's worth to say that too in the comments.
 
@sachin: while it looks fine for me, someone from the general server should have a look - maybe Bar is enough. What bothers me a bit is whether it's better to indicate those part-of-the-name '.' with \.? Not-slashed one would be indeed the option struct connector.
