Fix a bug for sort. When the key_separator is not space, the sort commandline tool fails to sort by the 3rd,4th,etc column. For example: when you exec
$ sort -t',' -k 3n
on a file which cotains:
1,2,3,4
2,3,4,1
4,1,2,3
3,4,1,2
you got:
4,1,2,3
1,2,3,4
2,3,4,1
3,4,1,2
but the expected output should be:
3,4,1,2
4,1,2,3
1,2,3,4
2,3,4,1
The bug is due to the dependency of "isspace(str[end])" at line 113.
When searching for the non-space key_separator, the search stopped just at the position of first key_separator it met.
The bug can be easily fixed by adding "end++" when the search have found one separator and exit the for loop.
