Document whichwrap for text expander (Espanso/AutoHotkey) compatibility

[gitdexgit]

When a replacement requires moving the cursor back across a line boundary, external text expansion tools (like Espanso or AutoHotkey) fail in Neovim.

By default, Neovim blocks the and arrows from wrapping lines in Insert mode --> This causes expanders to "get stuck" at the start of a line. Not ideal.

The Fix:

vim.opt.whichwrap:append("[,],b")

Proposal:
Add this to the official FAQ or a "Compatibility" section in the Wiki. Modern workflows using global text expanders are common, and this "hidden" default behavior is a major friction point for new users.

It took me 9 months to figure this out(I didn't know how text expanders move cursor :D). Also LLM was of no help it kept hallucinating over and over.

Btw Emacs Evil mode has vim.opt.whichwrap:append("[,],b") by default just saying:
