Strict Paredit indentation gives errors with tab characters

[tohoyn]

Hello

The "Paredit: Indent" VSCode command does not work with tab characters. To reproduce the bug do the following:

1. Get file argtest1.scm.
2. Open the file with VSCode.
3. Give VSCode command "Convert Indentation to Tabs".
4. Give VSCode command "Paredit: Indent".
