t5300: confirm failure of git index-pack when non-idx suffix requested
2e0c3ed 
Add test case to demonstrate that `git index-pack -o <idx-path> pack-path`
fails if <idx-path> does not end in ".idx" when `--rev-index` is
enabled.

In e37d0b8 (builtin/index-pack.c: write reverse indexes, 2021-01-25)
we learned to create `.rev` reverse indexes in addition to `.idx` index
files.  The `.rev` file pathname is constructed by replacing the suffix
on the `.idx` file.  The code assumes a hard-coded "idx" suffix.

In a8dd7e0 (config: enable `pack.writeReverseIndex` by default, 2023-04-12)
reverse indexes were enabled by default.

If the `-o <idx-path>` argument is used, the index file may have a
different suffix.  This causes an error when it tries to create the
reverse index pathname.

The test here demonstrates the failure.  (The test forces `--rev-index`
to avoid interaction with `GIT_TEST_NO_WRITE_REV_INDEX` during CI runs.)

index-pack: disable rev-index if index file has non .idx suffix
0eb81d0 
Teach index-pack to silently omit the reverse index if the
index file does not have the standard ".idx" suffix.

In e37d0b8 (builtin/index-pack.c: write reverse indexes, 2021-01-25)
we learned to create `.rev` reverse indexes in addition to `.idx` index
files.  The `.rev` file pathname is constructed by replacing the suffix
on the `.idx` file.  The code assumes a hard-coded "idx" suffix.

In a8dd7e0 (config: enable `pack.writeReverseIndex` by default, 2023-04-12)
reverse indexes were enabled by default.

If the `-o <idx-path>` argument is used, the index file may have a
different suffix.  This causes an error when it tries to create the
reverse index pathname.

Since we do not know why the user requested a non-standard suffix for
the index, we cannot guess what the proper corresponding suffix should
be for the reverse index.  So we disable it.

The t5300 test has been updated to verify that we no longer error
out and that the .rev file is not created.

TODO We could warn the user that we skipped it (perhaps only if they
TODO explicitly requested `--rev-index` on the command line).
TODO
TODO Ideally, we should add an `--rev-index-path=<path>` argument
TODO or change `--rev-index` to take a pathname.
TODO
TODO I'll leave these questions for a future series.

Looks like a solid band-aid to me.
