[TxMt] Indentation question

[Gerd Knops]

Question:

In the C bundle I disable indentation by setting

{	decreaseIndentPattern = '(?=not)possible';
	increaseIndentPattern = '(?=not)possible';
	indentNextLinePattern = '(?=not)possible';
	unIndentedLinePattern = '(?=not)possible';
}

Now I have this (pipe denotes cursor, \t is a tab):

{
\t|
}

As soon as I type any character, the tab disappears. Why?
