Langmap and delimitMate - backticks instead of closing square brackets

[pshvechikov]

I dont know whether it is a bug or not.

When using langmap such as this

set langmap=йq,цw,уe,кr,еt,нy,гu,шi,щo,зp,х[,ъ],фa,ыs,вd,аf,пg,рh,оj,лk,дl,э'
set langmap+=яz,чx,сc,мv,иb,тn,ьm,ю.,ЙQ,ЦW,УE,КR,ЕT,НY,ГU,ШI,ЩO,ЗP,Х{,Ъ},ФA,ЫS
set langmap+=ВD,АF,ПG,РH,ОJ,ЛK,ДL,ЯZ,ЧX,СC,МV,ИB,ТN,ЬM,Ж:,Б<,Ю>,]`,[~
set langmap+=\\,^

i get delimitMate plugin working properly except of closing [ character. Here is the problem in my test of delimitMate plugin. It is worth to say, that this is only one problem that appears with langmap.
