bug#25545: 26.0.50; long values in *Help* are truncated

[Mark Oteiza]

From -nw -Q in a terminal of width 80:

1. Insert into *scratch*:

  (defcustom my-long-defcustom-name-for-reasons-foo 'a-long-variable-name-because
    "A docstring"
    :type 'variable)

2. Evaluate it
3. C-h v RET my-long-defcustom-name ... RET

The *Help* buffer's first two lines are

my-long-decustom-name-for-reasons-foo\x19s value is
a-long-variable-name-becaus

missing the ultimate letter "e".  I had noticed this in some long string
values where the ultimate double quote was missing.

FWIW, I don't see that in this release.  Maybe a regression?

Thanks, should be fixed now.
