It's also covered by compare-strings, but both need a bit of setup to do the 
same as s-shared-start, so a wrapper can be useful (for example, it's easy to 
forget to reset completion-regexp-list). Additionally, discovering the right 
function to call can be hard (I hadn't realized that try-completion could be 
used for this, and neither had the authors or s.el).
