git grep --show-function treats GOTO labels as function names

Git grep is an amazing tool, and --show-function makes it very easy to create reports that contain not only line information, but the containing function as well.

It looks like there is an issue with how the parser handles "goto" labels, as it treats them the same as a function name.

In the example below, there is only one function, with two matches, but using --show-function indicates there are two function names.

$ cat test2.cpp
int main() {
    FOO
exit:
    FOO
}

$ git --version git version 2.26.2

$ git grep --no-index --show-function -e FOO test2.cpp test2.cpp=1=int main() { test2.cpp:2: FOO test2.cpp=3=exit: test2.cpp:4: FOO
