Yes, you're right. I forgot about them.

Yeah, but not everyone - switch sh to ksh (from pdksh) and try to
interrupt this script without kill -9 ;-)
Anyway - every distro with sh linked to bash should be assumed to be
broken. Additionaly bash is slow, much slower than pdksh or zsh is,
what can be especially noticed when running configure scripts.

In this situation it was easier to fix yours. I applied these 3 points
(fixed locking echo, removed excessive cut to make script a bit faster
and shortened grep) and changed copy mark from "x" to "" in order to use
-z and -n tests.
Oh, sorry for reformated spacing - I was working on my copy:/ I hope it
won't be a problem to do diff -iwB, would be?
