AWK: read the next line

getline, the function reads the next line and moves the script to it.

I wanted to get the current git version number from https://git-scm.com/downloads, and using getline came very handy by running something like this:

curl --silent https://git-scm.com/downloads | awk '/span class="version"/ {getline; print $1}'

I'm able to get the latest version number.
