HT means "horizontal tab", like might be shown with "man ascii".

Git uses tabs for indentation.  This file is documentation instead of
source so clang-format doesn't know about it, but I might as well
mention anyway: if you run "make style", then clang-format will give
some suggestions around formatting.  The configuration for that is not
yet perfect so you can take its suggestions with a grain of salt, but
they should get you in the right direction.

Yes, DEVELOPER_CFLAGS includes -Wdeclaration-after-statement.

By leaving it uninitialized, you can help avoid the reader wondering
whether there is some code path where the default value is used.

Let's see: *checks with "git grep -e TZ -- t"*.

Looks like t0006 tests various aspects of TZ handling pretty well and
t1100 includes of test using TZ with commit-tree (good).

Thanks and hope that helps,
