elideAccountName :: Int -> AccountName -> AccountName

Elide an account name to fit in the specified width. From the ledger 2.6 news:

  What Ledger now does is that if an account name is too long, it will
  start abbreviating the first parts of the account name down to two
  letters in length.  If this results in a string that is still too
  long, the front will be elided -- not the end.  For example:

    Expenses:Cash           ; OK, not too long
    Ex:Wednesday:Cash       ; Expenses was abbreviated to fit
    Ex:We:Afternoon:Cash    ; Expenses and Wednesday abbreviated
    ; Expenses:Wednesday:Afternoon:Lunch:Snack:Candy:Chocolate:Cash
    ..:Af:Lu:Sn:Ca:Ch:Cash  ; Abbreviated and elided!
