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.)

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.

git index-packfails when the-oargument is used and the requested.idxfile does not have the standard.idxsuffix because the reverse index code expects a.idxsuffix when it generates the.revfile name.Let's just silently disable the reverse index when the suffix is different from
.idx.This has been in the
microsoft/gitfork of Git for over half a year now, via microsoft#599, and it is time that this bug fix is upstreamed.
