@vfaronov Many thanks for testing.

Regarding the bug. I assume PATH_MAX is just 260 on Windows. I've read http://insanecoding.blogspot.de/2007/11/pathmax-simply-isnt.html and it appears PATH_MAX is pretty broken in general.

The tag data contains the full path name. Apparently it contains something weird (non-null) if it exceeds PATH_MAX, while from the code I'd think it contains NULL (but that would crash Geany). To be sure, please check with the following diff.

In any case, this is a separate issue. We have our own realpath() on windows which doesn't handle this case. The the underlying data this PR uses is already wrong. You should see the error message about utils_tidy_path() even without my patch.
