Makes sense.

optional: this could be part of the same expression:
help = !(p->option & NO_INTERNAL_HELP) && argc == 2 && ...;

Hm, I don't see any instances of "grep -f" in the testsuite. Are
there portability pitfalls in it I don't know about? It's in POSIX,
so it looks pretty safe.
I would have been tempted to use comm, which is already used in
t6500-gc.sh:
comm -1 -3 no_internal_help builtins >builtins_internal_help
Other nits:
- preparatory 'cat' commands like the above tend to go inside
test_expect_success these days
- test that set up for later tests get marked as 'setup' or 'set up'
With whatever subset of the changes below looks good squashed in,
