Strcoll fails sorting string with multiple words

[Mathias Gruber]

Hi,

I was testing PostgreSQL using Linux and found a strange bug when sorting
strings using collation.
First I considered this was a bug with that package. But after a long
research I found that the strcoll() function made the strange behavior.
The problem occurs when sorting string with multiple words. The routine
sorts the strings skiping blanks!

I've attached a sample C code that illustrates the problem. I reproduced the
problem using RH Linux 7.

Just compile the program and set the LC_ALL variable to any western language
(I've used pt_BR).

Best Regards
