Teach git-tag about showing tag annotations.
The <pattern> for -l is now a shell pattern, not a list of grep parameters.
Option -l may be repeated with another <pattern>.
The new -n [<num>] option specifies how many lines from
the annotation are to be printed.
Not specifieing -n or -n 0 will just produce the tag names
Just -n or -n 1 will show the first line of the annotation on
the tag line.
Other valuse for -n will show that number of lines from the annotation.
The exit code used to indicate if any tag was found.
This is changed due to a different implementation.
A good way to test a tag for existence is to use:
git show-ref --quiet --verify refs/tags/$TAGNAME
