region save/restore

Browse Source 
When shortening/splitting wide lines I noticed that the save and
restore code for regions had a bunch of those and they could be
shortened by using an intermediate variable.  Easier to read too.

Also, change several 'unsigned int' to just 'unsigned' as is used in
most of the rest of the code.

At one point I omitted a (genericptr_t) cast (which should no longer
be necessary...) and discovered that bwrite() wasn't declaring the
input buffer it never modifies as 'const'.
