Ever since I figured out how to configure rxvt to put the scrollbar on
the right, I haven't used the "run bash from cmd.exe" console.
Nowadays, for Cygwin I use mintty exclusively.
Sometimes I run C:\cygwin17\bin\grep from the Windows prompt, but
that's not affected by CYGWIN=tty, right?

Anyway, I haven't had the CYGWIN env.var set for years, and never missed it.

What would that gain ? Would it speed up the rest of the code? Would
the rest of the code become cleaner, easier to understand/maintain?
