Accept multi line in Stash message like commit message

[BabcB]

Feature to accept multiline stash message like commit messages.

And when there is a multiline commit message written in Source Control Input Box and click on stash button it can accept that multiline message as stash message.

Thank you.

VS Code doesn't yet support multiline inputs yet.

hi! So just to have some reference, this is blocked by microsoft/vscode#98098 and @eamodio your PR microsoft/vscode#177045 aims to fix it, right?
