bug#39291: M-: history doesn't store erroneous input

[Paul Pogonyshev]

M-: (oops-i-forgot-to-type-the-closing-paren RET

=> End of file during parsing

Error itself is fine, but the problem is if you now

type M-: again, you won't find your input in the

history and have to retype everything from scratch

instead of just fixing the typo.

This is a regression in trunk compared at least to

26.3.
