Fish shell integration is broken in 1.111.0 with MSYS2 environment

[Bryan2333]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.111.0
• OS Version: Windows 11 25H2 (26200.7840)

Steps to Reproduce:

1. Make sure your fish shell load . (code --locate-shell-integration-path fish)
2. Just open the terminal inside vscode

Logs:

c:\Users\Bryan\scoop\apps\vscode\1.111.0\ce099c1ed2\resources\app\out\vs\workbench\contrib\terminal\common\scripts\shellIntegration.fish (line 128): Missing end to balance this function definition

This will not happen with 1.110.1

A temporary workaround is to modify function __vsc_escape_value like below

function __vsc_escape_value
	# Escape backslashes and semi-colons
	echo $argv | string replace --all '\\' '\\\\' | string replace --all ';' '\\x3b'
end
