[sane-devel] Xsane: update suggestion

[t.van at telfort.nl]

In the default settings of the  Epson Perfection 1250 scanner is a param
called:
  Warming time (Dutch: opwarmtijd).
In current version the value is 0.

But since the scanner needs some time to warm up, the scanner does NOT work.
When setting this to eg 10 (seconds), then the scanner works fine.
