```

So far git describe --match <pattern> would apply the <pattern> only
to tag objects not to lightweight tags. This change make describe apply
the <pattern> to lightweight tags too.

Thanks both.  I've reworded the log message to make it clear that this is
not a random new feature but is a bugfix.

Subject: [PATCH] describe: match pattern for lightweight tags too

The <pattern> given "git describe --match" was used only to filter tag
objects, and not to filter lightweight tags.  This fixes it.

[jc: made the log to clarify this is a bugfix, not an enhancement, with
additional test]
