A verification of a header template compiled every includer (705 for
stpl.h) and a merge every includer of every submitted header (up to 1199
per header), even when the header only differed in line endings; one
such job took up to an hour and held up every other batch. Now:
- merge: headers unchanged from main are skipped; for changed ones, the
includers whose source mentions a name the change touched (identifiers
on changed lines, the enclosing class/struct), all of them only when
that is more than 300;
- verification: the includers that mention the template arguments of
the annotation (or the class), at most 16.
