Maybe something like the following would help.

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 to avoid this confusion.
