From 1a0ca5e358c1af14160e610e346c706e5dccf535 Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Tue, 10 Jan 2017 14:19:48 +0530 Subject: ref-filter: modify the 'lstrip=' option to work with negative '' Currently the 'lstrip=' option only takes a positive value '' and strips '' slash-separated path components from the left. Modify the 'lstrip' option to also take a negative number '' which would strip from the left as necessary and _leave_ behind only 'N' slash-separated path components from the right-most end. For e.g. %(refname:lstrip=-1) would make 'foo/goo/abc' into 'abc'. Add documentation and tests for the same.
