ocp-indent library, "newline tokens" fork

This is a modified version of the ocp-indent library, which is based on a different lexer, using newline tokens and banning multi-line ones, which is more convenient for some applications.

The library is exported as ocp-indent-nlfork, so as not to interfere with canonical ocp-indent installations.

This package does not install an ocp-indent binary or related tools.
