I'd like to write an elisp function that tells me the line number of the closest regex match above my current cursor position.
For example, if my cursor is on line
9 of the following file and my regex pattern is
^george, then the line number is
1 john 2 paul 3 george 4 ringo 5 hello world 6 george ringo 7 john paul 8 hello george 9 paul 10 george
