I do not think there is any "mis" nor "nesting" here.  The -l option can
be used to tell the command to operate in "list tags" mode, and in that
mode it can use a pattern to limit the output (with or without --contains
<commit>).  All of these are supported:

    git tag -l --contains v1.7.0 v\*
    git tag -l v\*
    git tag --contains v1.7.0 -l v\*
    git tag -l v\* --contains v1.7.0

IOW, <pattern> is _not_ an optional argument to the -l option.  In fact, I
think we should support more than one patterns, even though currently this
seems to silently ignore k\*:

    git tag --contains v1.7.0 -l v\* k\*

As I tend to consider that "limit by pattern" is like pathspecs (in this
case, it is _not_ a pathspec, though), having the pattern at the end looks
the most natural, but it may be just me.  And that is why I think we ought
to accept and apply more than one patterns here.

I would further say that "git tag -l <pattern> --contains <commit>" should
be an error, even though the command currently seems to take it; perhaps
parameter reordering is in effect?  I didn't look closely enough.
