Currently, when a plain-text integer starts with a zero (which happens
sometimes due to zero-padding to have a fixed number of characters).
Gnuastro's text-reading library will interpret it as an octal base (which is
common in computer science). 

The problem can be reproduced with a simple table where the column is defined
to be an integer (the number 164 is the integer value when interpreting "0420"
in octal base).


$ cat test.txt 
# Column 1: id [counter ,uint8] test
0420

$ asttable test.txt 
164


This problem was reported by Manuel Sánchez-Benavente (in the context of
reading FITS keywords, but the origin of the problem is the same as above,
which is easier to reproduce).
