Subject: [PATCH 2/3] add msys2 launcher
Also makes mintty pinnable to Windows Taskbar.
Before, a pinned shortcut would have generic icon and fail to launch a
proper shell because of $MSYSTEM not being set.
The list of shells is harcoded. An editable config file in /etc would
be nice (for e.g. "MSYS2 zsh" item), but this works for now.
Usage notes:
If the taskbar cannot forget mintty's default icon, rebooting helps
(at least, non-fast-restart one).
If the taskbar cannot forget the mintty's default "Terminal" tooltip
text displayed upon mouse hover of the shorcut, deleting the
[HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\Shell\MuiCache]
"C:\\path\\to\\msys\\usr\\bin\\mintty.exe.FriendlyAppName"
registry value (or just the entire MuiCache directory) should help, at
least for the current Windows 10.
