I added recursive match operators, "\{" (start of repetition) and "\}" (end of
repetition) at revision 3012.

/\{dir\}/ matches more than or equals to 1 repetition of dir (e.g. /dir/
/dir/dir/ /dir/dir/dir/ /dir/dir/dir/dir/ ).

The "\{" operator is permitted in the form of "/\{" sequence only.
The "\}" operator is permitted in the form of "\}/" sequence only.
No '/' is permitted between "\{" and "\}" operators.

Some examples:

/home/vladap/software/firefox/firefox/\{\*\}/\*.dat
/var/www/html/\{\*\-.\*\}/\*.html
/var/www/html/\{\*\-.\*\}/public/\*.html
