Subject: fsck: test and document unknown fsck.<msg-id> values
X-Git-Tag: v2.19.0-rc0~56^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8a6d0525b74fe07bde0436e4cbf87b23adf7df0a;p=thirdparty%2Fgit.git

fsck: test and document unknown fsck.<msg-id> values

When fsck.<msg-id> is set to an unknown value it'll cause "fsck" to
die, but the same is not true of the "fetch" and "receive"
variants. Document this and test for it.
