Covers both begin_export/end_export blocks and single-line export
pragmas.
Like with 'IWYU pragma: keep' marks the forward decl as automatically
desired to avoid removing manually exported but unused decls.
Add a simple testcase and update documentation.
this was a proposed issue in #1095 where one could
make a block of keeps as opposed to marking every
keep with a pragma: keep instruction.
added test to verify and updated documentation
where appropriate.
Sometimes IWYU's auto-detection of associated headers is insufficient.
Add an IWYU pragma to explicitly set associated header.
This is based on an original patch by Ivan Koster.
I added a test and some documentation.
