commit a96954b982ddd441ac943bfa48015fb4775c00cb
Author: Sean Whitton <spwhitton@spwhitton.name>

icomplete-completions: Revise computation of prospects-len
* lisp/icomplete.el (icomplete-completions): Revise computation of
prospects-len (i) to avoid calling string-width on the entire
buffer-string, which could be slow; and (ii) to better handle minibuffer
prompts with embedded newlines (bug#72826).
