WTF, redirecting stderr (file descriptor number 2) to /dev/null should have
silenced git-rev-list in case of errors.
Compare
$ git rev-list foo --
fatal: bad revision 'foo'
with
$ git rev-list foo -- 2>/dev/null
which gives no output.
I wonder what shell does gitweb use if run from com.google.gerrit.httpd
as servlet...

That is because those views defaults to HEAD, which doesn't point to
a valid commit because 'master' branch it does point to doesn't have any
commits on it. They should probably be disabled (grayed-out, and made
ordinary text and not hyperlink) if HEAD is invalid.
But this would require more work than those patches.

That is because if you select some branch, then all those views use
currently selected branch (passed via URL, e.g. 'h' or 'hb' parameter
in case of query-params URL).
