There seems to be some internal stack overflow detection in MSVC's
`malloc()` machinery that seems to be independent of the `stack reserve`
and `heap reserve` sizes specified in the executable (editable via
`EDITBIN /STACK:<n> <exe>` and `EDITBIN /HEAP:<n> <exe>`).
In the newly test cases added by `jk/tree-name-and-depth-limit`, this
stack overflow detection is unfortunately triggered before Git can print
out the error message about too-deep trees and exit gracefully. Instead,
it exits with `STATUS_STACK_OVERFLOW`. This corresponds to the numeric
value -1073741571, something the MSYS2 runtime we sadly need to use to
run Git's test suite cannot handle and which it internally maps to the
exit code 127. Git's test suite, in turn, mistakes this to mean that the
command was not found, and fails both test cases.
Here is an example stack trace from an example run:

I verified manually that `traverse_trees_cur_depth` was 562 when that
happened, which is far below the 2048 that were already accepted into
Git as a hard limit.
Despite many attempts to figure out which of the internals trigger this
`STATUS_STACK_OVERFLOW` and how to maybe increase certain sizes to avoid
running into this issue and let Git behave the same way as under Linux,
I failed to find any build-time/runtime knob we could turn to that
effect.
Note: even switching to using a different allocator (I used mimalloc
because that's what Git for Windows uses for its GCC builds) does not
help, as the zlib code used to unpack compressed pack entries _still_
uses the regular `malloc()`. And runs into the same issue.
Note also: switching to using a different allocator _also_ for zlib code
seems _also_ not to help. I tried that, and it still exited with
`STATUS_STACK_OVERFLOW` that seems to have been triggered by a
`mi_assert_internal()`, i.e. an internal assertion of mimalloc...
So the best bet to work around this for now seems to just lower the
maximum allowed tree depth _even further_ for MSVC builds.

git merge-file knows how to merge files on the file system already. It
would be helpful, however, to allow it to also merge single blobs.
Teach it an `--object-id` option which means that its arguments are
object IDs and not files to allow it to do so.
We handle the empty blob specially since read_mmblob doesn't read it
directly and otherwise users cannot specify an empty ancestor.

`git merge-file` takes three positional arguments. Each of them is
documented as `<foo-file>`. In preparation for teaching this command to
alternatively take three object IDs, make these placeholders a bit more
generic by dropping the "-file" parts. Instead, clarify early that the
three arguments are filenames. Even after the next commit, we can afford
to present this file-centric view up front and in the general
discussion, since it will remain the default one.

Back in 32f3c541e3 (multi-pack-index: write pack names in chunk,
2018-07-12) the MIDX's "Packfile Names" (or "PNAM", for short) chunk was
described as containing an array of string entries. e0d1bcf825 notes
that this is the only chunk in the MIDX format's specification that is
not guaranteed to be 4-byte aligned, and so should be placed last.
This isn't quite accurate: the entries within the PNAM chunk are not
guaranteed to be 4-byte aligned since they are arbitrary strings, but
the chunk itself is 4-byte aligned since the ending is padded with NUL
bytes.
That padding has always been there since 32f3c541e3 via
midx.c::write_midx_pack_names(), which ended with:
i = MIDX_CHUNK_ALIGNMENT - (written % MIDX_CHUNK_ALIGNMENT)
if (i < MIDX_CHUNK_ALIGNMENT) {
unsigned char padding[MIDX_CHUNK_ALIGNMENT];
memset(padding, 0, sizeof(padding))
hashwrite(f, padding, i);
written += i;
}
In fact, 32f3c541e3's log message itself describes the chunk in its
first paragraph with:
Since filenames are not well structured, add padding to keep good
alignment in later chunks.
So these have always been externally aligned. Correct the corresponding
part of our documentation to reflect that.

e0d1bcf825 (multi-pack-index: add format details, 2018-07-12) describes
the MIDX's "PNAM" chunk as having entries which are "null-terminated
strings".
This is a typo, as strings are terminated with a NUL character, which is
a distinct concept from "NULL" or "null", which we typically reserve for
the void pointer to address 0.
Correct the documentation accordingly.
