First version of paths in ignore_files

Works correctly and the logic seems sound even if somewhat quirky.

`^%.` match any file of directory whose basename begins with a dot.

`^/node_modules$/"` match a directory named `node_modules` at the project's root.

  Note that the final '/' needs to be at the end. The '/' after the '^' needs to be there to trigger
  a match of the full path filename so we are sure it is at the root.

  PROBLEM: the '/' to trigger full path match could be in a pattern's special expression like:
  [^/]

`^%.git$/` match any directory name '.git' anywhere in the project.

`^/%.git$/` match a directory named '.git' only at the project's root.

`^/subprojects/.+/` match any directory in a top-level folder named "subprojects".

`^/build/` match any top level directory whose name begins with "build"

  PROBLEM: may be surprising, one may expects it matches only a directory named 'build'. It actually acts like
  it was `^/build.*/`.
