uncompress vs. write-file

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

With "uncompress" loaded, when writing a buffer to a file name ending
in ".gz" the buffer is uncompressed before writing.  This is wrong
because the command typed by the user explicitly specifies
writing "bar.gz" but instead "bar" was written.  In this
example, the contents of the buffer were not written
and "gunzip: stdin: not in gzip format" was written
to the file instead.  This makes no sense.

ls -alt foo* bar*
-rw-rw----  1 devon  devon    35 Dec 23 21:04 bar
-rw-r--r--  1 devon  devon   198 Dec 23 21:03 foo.gz
