symbolic links, unreadable files, skip

[Marcus Harnisch]

• What is your environment (OS)?

Red Hat Enterprise Linux release 6.6 (Santiago)

• Which version of GLOBAL are you using?

gtags (GNU GLOBAL) 6.5

• What did you do? (command line)

gtags --gtagslabel myconfig --explain >& gtags.log

• What was occurred? (as is)

In a rather huge and tangled directory tree, for which I have not the permissions necessary to clean up, gtags fails when encountering files which are unreadable according to my user permissions. Some of these are non-existent (or otherwise unreadable) link targets.
Including the link target in skip doesn't have any effect.

• What did you expect from it?

1. There should be an option for skipping files that can't be read.
2. It should be possible to apply skip rules to both, the link itself and the link target. Example: There could be many individual links (difficult to capture in skip), all pointing to somewhere inside an unreadable directory tree.
