emacs capitalizing every word in replacement how to prevent

[John Covici]

Hi.  I have a shell script like this
JawMuscles1
followed by other similar names.

I wanted to replace each item in the file like this:

Replace regexp (default ^.*$ → cd jawstemp; unzip ../\&.zip;mkdir
../\&;mv * ..\&;cd ..

but Emacs capitalized every word in the replaced lines, including all
the commands -- it replaced  unzip with Unzip etc.

I have never seen this before.  The file is type shellscript.

How to prevent this?

Thanks for any suggestions.
