Re: Possible ZSH bug involving piping ls to less (MSYS2 & Cygwin)

[<agkozak@xxxxxxxxx>]

I'm pretty sure it's been happening intermittently for quite a while, but I
couldn't say for sure when it started. Sorry.

I found a discussion on GitHub of a similar problem where git was being
piped to tig:

    https://github.com/jonas/tig/issues/951

They seem to think they know exactly when the problem started, but I can't
confirm that.

The workaround of using a subshell seems to help, i.e.

    ls --color | (less -R)

Yes, it happens quite frequently on MSYS2.

Has this been happening for a long time, or started to happen rather
recently?
(my experience on MSYS2 is quite limited)
