Bug#460897: vim: please improve syntax based folding of c/c++ comments

[Helmut Grohne]

Package: vim
Version: 1:7.1-175+2
Severity: wishlist
Tags: patch

I'm using syntax highlighting and foldmethod=syntax on C++ files. Let me
give an example:

/**
 * This is a doxygen comment.
 * ...
 */

This gets folded to:

+--  4 lines folded -----...

It would be much better to see the first useful line of the comment.
This can be achieved using a foldtext function like:

fun My_c_fold_line()
        let line = getline(v:foldstart)
        if line =~ '^\s*/\*\*\?\s*$'
                return getline(v:foldstart+1)
        else
                return line
        endif
endfun

It would be great if you could incorporate this or an improved version
in the syntax files.
