cat file for r.mapcalc

[Xin Zhuang]

I tried with r.patch and found out r.patch mislabel the cats.
I was trying to merge block layers from two counties.
Somehow r.patch assigned some cats crossing counties.
Maybe a bug in r.patch?

I modified r.cross with fs (not reruied). The original
r.cross uses semicolon (;) to separate cats from
dirrerent layers. With fs, you can have many other choices.
Here's syntax
	r.cross input=[files....] output=file fs=[character|SPACE|semicolon]


I enclosed a patch at the end of this message.
