this has subsequently been interpretted as:
* the following call sequence: sane_start; sane_read (repeat until
* EOF); sane_start; sane_read... and then call sane_cancel if the
* batch is at an end. I.e. do not call sane_cancel during the run but
* as soon as you get a SANE_STATUS_NO_DOCS.
sane_cancel should only be called at the end of the batch, not between
pages. XSANE is correct. i bet you are using scanimage from sane
1.0.17 or before, as the version that is part of sane 1.0.18 no longer has
bug in hpaio, imho.
