Subject: [PATCH v3] gitweb: clarify search results page when no matching commit found
Message-ID: <20100807215647.GB2969@burratino>
In-Reply-To: <AANLkTikiVQCMKjftWfrKbK-K+Gv45CTunxjULGc1==Zb@mail.gmail.com>

When searching commits for a string that never occurs, the results
page looks something like this:

	projects / foo.git / search                                 \o/
	summary | ... | tree          [commit] search: [ kfjdkas ] [ ]re
	first ⋅ prev ⋅ next

	Merge branch 'maint'

	Foo: a demonstration project

Without a list of hits to compare it to, the header describing the
commit named by the hash parameter (usually HEAD) may itself look
like a hit.  Add some text (“No match.”) to replace the empty
list of hits and avoid this confusion.

While at it, remove some nearby dead code, left behind from a
simplification a few years ago (v1.5.4-rc0~276^2~4, 2007-11-01).

changes relative to v2[1]:
 - better newline placement in the produced HTML.

Hopefully third time’s the charm.  Test reports welcome as always.
