The logic for the -b mode, where [PATCH] is dropped but [foo] is not,
silently ate all spaces after the ].
Fix this by keeping the next isspace() character, if there is any.
Being more thorough is pointless, as the later cleanup_space() call
will normalize any sequence of whitespace to a single ' '.
