[PATCH v5 0/8] allow non-trailers and multiple-line trailers

[Jonathan Tan <jonathantanmy@google.com>]

I've updated patch 5/8 to use strcspn and to pass in the list of
separators, meaning that we no longer accept '=' in file input (and also
updated its commit message accordingly).

We also discussed inlining find_separator, but after looking at the
code, I think that it is more convenient if find_separator returns -1
when there is no separator, because of the 3 times it is used (as
of 8/8), it is checked twice with '>= 1' (since both "no separator" and
"string begins with separator" are handled in the same way - treating
them as a non-trailer line). So I have left it as its own function.

No other updates.

Jonathan Tan (8):
  trailer: improve const correctness
  trailer: use list.h for doubly-linked list
  trailer: streamline trailer item create and add
  trailer: make args have their own struct
  trailer: clarify failure modes in parse_trailer
  trailer: allow non-trailers in trailer block
  trailer: forbid leading whitespace in trailers
  trailer: support values folded to multiple lines
