gitweb.js: fix padLeftStr() and its usage

It seems that in Firefox-3.5 inserting   with javascript inserts the
literal   instead of a space. Fix this by inserting the unicode
representation for   instead.

Also fix the off-by-one error in the padding calculation that was
causing one less space to be inserted than was requested by the caller.
