Subject: 28.0.50; handwrite produces invalid postscript output, needs a space
Date: Sat, 14 Nov 2020 16:02:29 -0600

I discovered today the `handwrite' command which produces postscript
output than renders the current buffer in a handwritten style.  I tried
it only discover my postscript viewer couldn't open the resulting file,
signaling an error: "undefined ashowpage".

I manually added a space to the single occurrence of "ashowpage",
turning it into "a showpage" and now the postscript file works in my
viewer.

So it seems that simply changing line 244 of handwrite.el from

    (insert "showpage exec Hwsave restore\n\n")

to

    (insert " showpage exec Hwsave restore\n\n")

will fix this bug.

Yup; I can confirm both the problem and that this fixes the bug, so I've
now installed this in Emacs 28.
