 I was looking through the nodejs portfile and came across this recursive
 glob function:
 {{{
 proc rec_glob {basedir pattern} {
     set files [glob -directory $basedir -nocomplain -type f $pattern]
     foreach dir [glob -directory $basedir -nocomplain -type d *] {
         eval lappend files [rec_glob $dir $pattern]
     }
     return $files
 }
 }}}
 It would be useful to have this proc available in base so I wouldn't have
 to copy it from the nodejs portfile if I ever want to use it myself.
