Description

This example behaves poorly:

less +F -S --follow-name some_log_file.log

https://explainshell.com/explain?cmd=less+%2BF+-S+--follow-name+some_log_file.log

I didn't have time to check, but iirc vi/vim/neovim have a similar "run command at startup with +flag type of thingie, which I will assume has a similar failure-mode. )=

Research direction

Reproduce the reported less command and trace how the parser handles the plus-prefixed argument. Check whether the same failure applies to vi, vim, or neovim-style startup arguments; done means these arguments are parsed without the reported poor behavior.
