Fix handling of truncated legacy errorpage %codes (#2411)

When build.input ends with a bare percent character, we must only
copy/consume that character and increment build.input by 1, not 2.

This overread bug existed since errorpage templates were introduced in
1997 commit 9b312a19. 2010 commit 4d16918e significantly broadened the
kinds of use cases that can trigger this bug.
