[libvirt] [PATCH 3/5] maint: enforce no-markup policy wrt VIR_WARN-like macros

[Jim Meyering]

From: Jim Meyering <meyering at redhat.com>

* cfg.mk (sc_prohibit_gettext_markup): New rule, to enforce
this policy.  Contrary to most diagnostic-emitting functions,
where we require _(...) markup, here, we require that _() *not*
be used for certain functions (or function-like macros).
