# NOTE: the effect of 'data set' and 'attr add' of a partially matched rule (above) persists through the rest of the rules!
#
# From the plumb(7) manpage:
# "Such rewritings are permanent, so rules that specify them should
# be placed after all pattern-matching rules in the rule set."
#
# yrk: I haven't found a way to avoid that, as I need to capture
# context from both 'data matches' and 'wdir matches' for the 'arg isfile' there.
