bug#63881: 29.0.91; apropos-documentation fails when load-history contains element whose CAR is nil

[Matt Beshara]

I’ve encountered this same bug too.  The real-life use case where 
I’ve run into it has been when attempting to use 
‘apropos-documentation’ after doing ‘eval-buffer’ in an EWW buffer 
containing only Elisp code, usually from e.g. GitHub.
