I would use string-join for this:

<xsl:sequence select="string-join($headers,$field-separator)"/>

The for-each loop is not needed.

Someone can correct me but I believe in your code the rules for sequence
construction come into play meaning that the string result of a sequence
always includes a space between items, so you're creating a sequence of
("A", "\t", "B"), which becomes "A \t B".
