Hooray, and welcome back from hibernation!!!

I (a would-be user of SANE-OS2) believe I've tried inserting "#option
no precal" into the "microtek.conf" file, but to no avail. Even though
the list of capabilities reported by the E3 does include
precal-suppression, every "scanimage" run seems to start with a precal.

Of course, many aspects of configuration seem to be different when one
compares Linux-SANE and OS/2-SANE, (probably because the filesystems
themselves are so different), so maybe Yuri can reassure us whether/how
"#option ..." lines actually get processed?
