I am of two minds there. In some cases, the newly added test demonstrates
the intended usage, and therefore makes for a nice documentation. In other
cases, the new test is large enough to stand on its own, i.e. to merit a
separate patch (also to make reviewing easier).

In this particular case, I tend to the latter: it is large enough a patch
that it is easier to review as a separate patch.

True. The proliferation of executables in t/helper/ got a little out of
hand.

But there is nothing preventing us from consolidating a few of them into a
single executable, using our wonderful option parsing function with
OPT_CMDMODE to switch between the different functions.

I could see, for example, how we could consolidate all string-related
test helpers into a single one, say, test-strings:

t/helper/test-ctype.c
t/helper/test-regex.c
t/helper/test-strcmp-offset.c
t/helper/test-string-list.c
t/helper/test-line-buffer.c
t/helper/test-urlmatch-normalization.c
t/helper/test-wildmatch.c

Also, these helpers seem to be related to index handling and could go into
a new test-index helper:

t/helper/test-dump-cache-tree.c
t/helper/test-dump-split-index.c
t/helper/test-dump-untracked-cache.c
t/helper/test-index-version.c
t/helper/test-scrap-cache-tree.c

Ciao,
Johannes
