indenting zsh files in vim

Currently, if you start a function with the function keyword, the function body is not indented. The following line (added the last OR condition) will result in functions being indented.

elseif line =~ ‘^\s*\<\k\+\>\s*()\s*{‘ || line =~ ‘^\s*{‘ || line =~ ‘^\s*function ‘

Not sure whom to contact to get this fixed, or else each update will result in the change being overwritten.
