v flags/modifiers in scripts/tags.sh

Hi,

I have a question about v flags/modifiers in scripts/tags.sh.

quoted from scripts/tags.sh:

exuberant()
{
...
--regex-c='/DEFINE_(MUTEX|SEMAPHORE|SPINLOCK)\((\w*)/\2/v/' \
...
}

emacs()
{
...
--regex='/DEFINE_HASHTABLE\((\w*)/\1/v/'
...
}

v is specified at the end of the regular expressions.

As far as I read the man pages of ctags and etags. there is no such
flags/modifiers. What is v?

(I am a co-maintainer of fishman-ctags, a fork of exuberant-ctags.
So I'm interested in implementing v flags in ctags if it is useful.)
