This is like -sizeToFit, except with a fixed width, so I think -sizeToFitWidth:
or -sizeToWidth would be appropriate.

Since you're in the midst of poking this, would you mind testing how
-setMinSize: and -setMaxSize: impact this?  It seems plausible/likely that if
the higher-level code did:
  [textView setMinSize:NSMakeSize(width, 0.0)];
  [textView setMaxSize:NSMakeSize(width, CGFLOAT_MAX)];
  [textView sizeToFit];
then it would get the appropriate results, without the shenanigans.  Does that
make sense?

[Sorry I didn't suggest this earlier - every time I review NSTextView and
NSText, I see some new thing which has only been around since OSX 10.0 or
something.]

Turns out minsize/maxsize don't bother sizeToFit that much - but setting a
frameSize of width/CGFLOAT_MAX works fine.
