Thanks! Right!
Hmmm. Well, it's natural to use find's -L option when making the
cscope.files, since compilers honor symlinks. Then again, maybe I use
cscope in strange ways; I want everything the compiler could possibly
get its dirty hands on, and I even throw in a libc tree, makefiles,
scripts, and the kitchen sink in there (yeah for the fuzzy parser).
So maybe all I needed was:
$ cscope -b
cscope: file foo.c is a symlink, ignoring it.
