Ah, that's where it was!  Thanks :)

I was mostly asking for the sake of people who find HTML unacceptable;
I'm mostly fine with it, though lines spanning the full window width are
somewhat hard to read.

After an hour fiddling with shr-width and gnus-html-frame-width to no
avail, I realized that the latter is only used with the gnus-w3m
renderer, while mm-shr let-binds the former to

(if shr-use-fonts
    nil
  fill-column)

This is surprising (to me), since shr-width's docstring says that an
integer value works just fine even when shr-use-fonts is set:

I've modified the snippet above to bind shr-width to fill-column
unconditionally, and it works wonders for me.  Maybe this condition
makes no sense anymore?  As things stand, if shr-use-fonts is set, the
user loses control over the line width.

WDYT?
