glob follows symlinks

[aplanas]

glob do not understand symlinks, and this cause problems in directories like /sys, where is frequent to have loops, and in some cases never ends.

Any review on #63 so I can improve the code?

[andre-richter]

I just hit this exact wall, looping infinitely in sys.

I think I'm not qualified to review, but when reading the code, I thought that follow_links might be a better name than follows_link.

Cheers, Andre

@andre-richter I think that you are right. I updated the PR. Thanks!
