VIM struct: foldinfo_T

Used to pass info about a fold from the fold-detection code to the code that displays the foldcolumn.

typedef struct foldinfo
{
    int         fi_level;       // level of the fold; when this is zero the
                                // other fields are invalid
    int         fi_lnum;        // line number where fold starts
    int         fi_low_level;   // lowest fold level that starts in the same
                                // line
} foldinfo_T;
