Gedit project: The error happens in SHA1 608d7a6b9b7f6d71376814ac7bbb450babe8882a because the directory project is empty, this is the second commit. Furthermore, this commit does not have a commit message, therefore we cannot use it. This error doesn't affect the results. This is the log of execution:

We can see that ctags is called with no files as the last parameter, that produces the No files specified error.

Make project: The error was because there was no .c or .h code to analyse in a commit. Now the script check this case. This error is fixed.

Screen project: This is similar to gedit project.
