Read TXT file with variable separation

Hi!

I have to import some TXT files into R, but the separation between the
columns are made with different blank spaces, but each file use the
same separation. Example:

31  104 5 0   11RUA                 SAO
SEBASTIAO                                                         25



 BAIRRO FILETO
                                                  01
                                                    00200338540000

The pattern is the same on each file.

There is two sample files attached to this message.

I would like to figure out how to import a single file, and the use
some code to import several files (like this
http://www.ats.ucla.edu/stat/r/code/read_multiple.htm)

When I try read.table, I receive this:

cnefe <- read.table("sample1.txt", header=FALSE)
Erro em scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  :
  linha 1 n?o tinha 17 elementos
