[PATCH] usrmount should skip comments in fstab

Hi!

Currently usrmount chokes on fstab lines like:
#... /usr ...
It will try to mount "#...", which obviously is wrong.

Attached patch fixes this by skipping over lines beginning with "#". It still 
does not handle cases like " #...", but is enough to work in my case.

Kind regards,
Dennis

This is not true if IFS contains the usual whitespaces, in which case read 
will already strip whitespace. So the patch should be safe for all cases.
