Code formatting does not obey editor.insertSpaces

[alexdima]

Moved from microsoft/vscode#3847
I have verified that we call on our side the format on type provider with the configured indentation options.

From @nixbb
It seems that the code formatter does not adhere to the indentation mode specified in the user settings.

Here's a simple example using version 0.10.10
In this case "editor.insertSpaces" is set to "auto" but this issue also manifests if it's set to false.

The example shows that all the indentation starts off as tabs.
The newly added line (line 11) is also indented using tabs.
When the statement is finished with a semicolon the current line and the next line is then indented with spaces.

Not shown in the gif is that an undo will revert line 11 and 12 to tabs instead of spaces.

Hope this helps narrow down the issue.

Any updates on this? It's incredibly annoying.

Is it alive?

Is this the reason that the "implement interface" uses spaces instead of tabs or should I file a new bug?

[0xdeafcafe]

@pavlos256 Same reason. It runs the format command on the relevant lines, which uses spaces.
