marp.exe rendering and watch mode do not work in msys on Windows 10 (i.e. git-bash)

[embix]

Version of Marp Tool

@marp-team/marp-cli v3.4.0 (w/ @marp-team/marp-core v3.9.0)

Operating System

Windows

Environment

• OS version: Windows 10 22H2 Build 19045.4291
• Node.js version: the one baked into Marp CLI, when using npx it's the rather rusty 17.9.0
• Shell Environment: msys/bash (git-bash as distributed with git 2.44.0 for Windows)

Bug occurs in marp.exe as well as when using npx @marp-team/marp-cli@latest

How to reproduce

1. open git-bash
2. create a minimal prez.md
3. either npx @marp-team/marp-cli@latest prez.md -o prez.html
   or /path/to/marp prez.md -o prez.html
4. it seems to freeze

marp --help or marp --version however work as expected. Using WindowsTerminal/Powershell works as expected.

Expected behavior

It should render the html/pdf or go into watchmode as requested and provide the usual [INFO]/[WARN] outputs accordingly.

Actual behavior

the msys terminal freezes

Additional information

Already tried running with MSYS_NO_PATHCONV=1 just in case it's related to msys's Posix path conversion but that didn't help.

Workarounds: Add --no-stdin option, or run CLI through winpty bridge.
