Weird `tagfiles()` behavior

[stellarhoof]

I don't think this issue goes here, but I don't know how to submit an issue to whatever bug tracker they use with Vim. Since I was looking at the code and saw that this plugin uses Vim's tagfiles() function, I thought @xolox could enlighten me. The issue is that Vim's tagfiles() function in my machine (7.4.488 with OS X 10.9.5) will only return the last entry in the &tags variable. Any idea why might this be?

Nevermind, for anyone who might encounter this issue the problem is that tagfiles() will

1. Parse &tags
2. Only include files in the list if they exist Leaving this open for the @xolox to close it. Maybe it will be useful to him.

Hi @azure-satellite. I agree the behavior of Vim's tagfiles() function can be confusing, however it is documented, although in a somewhat obscure fashion:

• The documentation of the tagfiles() function states:

  Returns a List with the file names used to search for tags for the current buffer. This is the 'tags' option expanded.

• The documentation of the 'tags' option states:

  The tagfiles() function can be used to get a list of the file names actually used.

The text "the file names actually used" implies that this only concerns existing tags files, but it is very implicit. So as I said, it's documented behavior, although it's a bit obscure. I will close this issue now because I don't think I can change anything about this.
