regex status report #8

[Gabor Kovesdan]

Hi,

I found and fixed a bug related to the BSD-specific REG_STARTEND 
extension. My fixed string matching code works now but there are some 
cases when it segfaults. Now I'm trying to investigate why it happens. 
In general, the code seems to scale well and I expect the fixed string 
matching to beat the NFA code if the pattern is long enough.

Apart from this, I built a small test framework and I added some test 
cases for BREs. I will add some more for EREs and in the future the 
GNU-specific extensions will have another test suite when they are 
implemented but it's a lower priority for now.
