Relatively straightforward - I'm happy to do this.  Presumably this
should be controlled by option -r, --regex for compatibility with
slocate.

Could you find out for me whether the slocate implementation requires
that the regexp match the 

1. The WHOLE path name, or 
2. Just the basename, or
3. Any substring?

c.f. GNU locate's -w and -b options.

Thanks,
