Issue: Delete all but ONE tab in a line.

Text looks something like this:
blah blah blah <tab> blah blah blah. <LF>
blah blah blah <tab> <tab> <tab> blah blah blah. <LF>
blah blah <tab> <tab> blah blah. <LF>

End result to look like:
blah blah blah <tab> blah blah blah. <LF>
blah blah blah <tab> blah blah blah. <LF>
blah blah <tab> blah blah. <LF>

Lines are delimited by hard returns. Document is quite small, typically no more than two pages.

Thanks.
