New file t/tree/issue134.c exercises the bugs noted in
<https://github.com/bootlin/elixir/issues/134#issue-624392766>.
I did not copy in the files listed in that comment because those files
are GPL-2.0-only or an unspecified GPL license, not GPL-2.0-or-later.
If the first function in a file does not have a doc comment, do not
run off the beginning of the file. Fixes#102.
Also:
- Add t/tree/issue102.c that exhibits this bug.
- in find-file-doc-comments.pl and script.sh, exit with a nonzero code
if this should recur.
These files all carry SPDX GPL2+ indicators. Based on the information
available to me, I have a good-faith belief that they can be combined
into this AGPLv3 project and licensed AGPLv3.
This commit only touches t/tree. Therefore, if the test suite later
needs to be changed, it will be sufficient to revert this commit.
The files used are those involved in the x64 compilation of
drivers/i2c/i2c-core-base.c, filtered to remove any that aren't
tagged GPL2+.
Note that t/tree itself is not a Git repo or submodule. It is a
collection of files that test scripts can use to populate a Git repo.
