" search.vim — buffer search: search()/searchpos() move the cursor to a pattern,
" searchpair()/searchpairpos() find a matching nested pair, searchcount() counts
" matches of the last pattern (ported from Neovim's search.c). These build on the
" in-memory buffer + cursor + the Vim regex engine, so they run standalone.
" Self-test: asserts into v:errors, throws at the end if anything failed.
