[BUG] commit message with tabulation characters

[Alexander Belchenko]

I edit commit message in external editor (FTE) and for some purposes I 
insert tab symbol for formatting my message. When I save message and 
exit from editor I saw that bzr report this:

D:\user\python\bzr\__test>bzr ci
added 1.txt
bzr: replaced 1 control characters in message

After that I want to see my log and see instead of expanded tab simply 
"\t" combination:

D:\user\python\bzr\__test>bzr log -r-1

revno: 1

message:
   First line
   \tspam

   ^^ - there is must be my tab character

I think it is bug but I'm not sure in which command (commit or log?) and 
how it should be fixed.
