Subject: [PATCH] clang-format: include kh_foreach* macros in ForEachMacros

From: René Scharfe <[email-masked]>
Date: Fri, 5 Jul 2024 21:25:43 +0200

The command for generating the list of ForEachMacros searches for
macros whose name contains the string "for_each".  Include those whose
name contains "foreach" as well.  That brings in kh_foreach and
kh_foreach_value from khash.h.

Regenerating the list also brings in hashmap-based macros added by
87571c3f71 (hashmap: use *_entry APIs for iteration, 2019-10-06),
f0e63c4113 (hashmap: use *_entry APIs to wrap container_of, 2019-10-06),
4fa1d501f7 (strmap: add functions facilitating use as a string->int map,
2020-11-05), b70c82e6ed (strmap: add more utility functions,
2020-11-05), and 1201eb628a (strmap: add a strset sub-type, 2020-11-06).

for_each_abbrev is no longer found because its definition was removed by
d850b7a545 (cocci: apply the "cache.h" part of "the_repository.pending",
2023-03-28).  Note that it had been a false positive, though, as it had
been a function wrapper, not a for-like macro.
