Introduced protected attribute for Fortran

[p-vitt]

The protected attribute in Fortran is used to make a module variable readable, but not editable from outside. However, public module variables marked with the protected attribute were omitted when the file was parsed. Therefore, I added the protected attribute.

Coverage remained the same at 84.412% when pulling b26dfca on p-vitt:fortran-protected into 3522685 on universal-ctags:master.

Looks probably good, but could you add a test case please?

Surprisingly protected attr and public attr can be used together in the same field :-0

Could you squash this commit("fixed typo") into the previous commit ("Added unit test for the protected attribute") to keep the history simple.

[p-vitt]

Sure, need to look up how to (I'm more used to mercurial), but I guess I'll find out :)

I'm more used to mercurial.
Oh, I see.

git rebase -i and git push --force may help you.

Thank you.
