When "branch" is given a list-like option, such as --contains, it implicitly provides --list. Before this change "tag" would error out on those sorts of invocations. I.e. while both of these worked for "branch": git branch --contains v2.8.0 git branch --list --contains v2.8.0 Only the latter form worked for "tag": git tag --contains v2.8.0 '*rc*' git tag --list --contains v2.8.0 '*rc*' Now "tag", like "branch", will implicitly supply --list when a list-like option is provided, and no other conflicting non-list options (such as -d) are present on the command-line. Spelunking through the history via: git log --reverse -p -G'only allowed with' -- '*builtin*tag*c' Reveals that there was no good reason for not allowing this in the first place. The --contains option added in 32c35cfb1e ("git-tag: Add --contains option", 2009-01-26) made this an error. All the other subsequent list-like options that were added copied its pattern of making this usage an error. The only tests that break as a result of this change are tests that were explicitly checking that this "branch-like" usage wasn't permitted. Change those failing tests to check that this invocation mode is permitted, add extra tests for the list-like options we weren't testing, and tests to ensure that e.g. we don't toggle the list mode in the presence of other conflicting non-list options. With this change errors messages such as "--contains option is only allowed with -l" don't make sense anymore, since options like --contain turn on -l. Instead we error out when list-like options such as --contain are used in conjunction with conflicting options such as -d or -v.
