keyword: do not expand at all during diff
Always shrink and never expand keywords during a diff operation.
Avoid user distraction e.g. because of spurious differences
appearing in the commit editor.
Basic install:
$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help
