Code review comment for lp:~gesha/linaro-license-protection/fix-https-and-chrome

I was here and eyeballed it for typos, etc.

Not sure I understand functionality enough to comment on that. One thing I could point to is:

+function check_file($fn)
70 +{
71 + if (is_file($fn) or is_link($fn)) {

if (file_exists($fn) and check_file($fn)) { // Requested download is file

Symlink is assumed to be a file, but it can point to a dir too.
