[PATCH 0/7] Comments and refactoring in attr.c

This patch series adds comments for some non-obvious things in attr.c,
simplifies the interface of parse_attr(), and unrolls the loop over
passes in parse_attr_line() (which IMO makes the code easier to
understand).  It does not change the observable behavior in any way.

The patch series is against master, but can be rebased to next without
conflicts.

Michael Haggerty (7):
  Add a file comment
  Document struct match_attr
  Increment num_attr in parse_attr_line(), not parse_attr()
  Change parse_attr() to take a pointer to struct attr_state
  Determine the start of the states outside of the pass loop
  Change while loop into for loop
  Unroll the loop over passes
