This was changed in patch 7.2.025:
Patch 7.2.025
Problem: When a CursorHold event invokes system() it is retriggered over
and over again.
Solution: Don't reset did_cursorhold when getting K_IGNORE.
Files: src/normal.c
You can use something like "f\e" instead:
autocmd CursorHold * call Timer()
function! Timer()
call feedkeys("f\e")
echo strftime("%c") " this for debugging
endfunction
This starts a "f" command and then cancels it with Esc.
Does that have more side effects? We could add something like CTRL-\
CTRL-N that doesn't do anything. Much better than using an undocumented
key code.
