Several misc cleanups, refactor main() to reduce size. Adds -v option to always fully expand variables (only interesting to NetBSD) And in particular (from ChangeLog): o meta.c: ensure command output in meta file has ending newline even when filemon not being used. When matching ${.MAKE.META.IGNORE_PATTERNS} do not use pathname via ':L' since any ':' in pathname breaks that. Instead set a '${.p.}' to pathname in the target context and use that.
