...now also covering variables with internal linkage that don't need a redundant
"static". (Unlike with functions, with variables there are also cases that are
not in an unnamed namespace, hence the rename of the plugin.)
All the relevant changes across the code base have been done in the preceding
"Upcoming improved loplugin:staticanonymous -> redundantstatic" commits.
Ideally the changes would have been done with a rewriting plugin, but it can be
quite tedious in general to identify the correct occurrence of "static" that
must be removed, consider e.g.
struct { int init() { static int n; return n++; } int x = init(); } static
const a[10] = {};
However, it turned out that in all cases across the code base, the relevant
"static" was either at the start of the declaration or came after an initial
"const". So I temporarily changed the plugin with

to report the diagnostics at the start of the declarations (instead of at a more
natural place which is typically somewhere in the middle of the declaration),

where necessary.)
