[PATCH 5/5] kernel-doc: make highlights more homogenous for the various backends

From: Paolo Bonzini
Date: Mon Jan 02 2017 - 10:23:04 EST


$type_struct_full and friends are only used by the restructuredText
backend, because it needs to separate enum/struct/typedef/union from
the name of the type. However, $type_struct is *also* used by the rST
backend. This is confusing.

This patch replaces $type_struct's use in the rST backend with a new
$type_fallback; it modifies $type_struct so that it can be used in the
rST backend; and creates regular expressions like $type_struct
for enum/typedef/union, for use in all backends.

Note that, compared to $type_*_full, in the new regexes $1 includes both
the "kind" and the name (before, $1 was pretty much a constant).
