+Tests for autocommands:
+- FileWritePre		writing a compressed file
+- FileReadPost		reading a compressed file
+- BufNewFile		reading a file template
+- BufReadPre		decompressing the file to be read
+- FilterReadPre		substituting characters in the temp file
+- FilterReadPost	substituting characters after filtering
+- FileReadPre		set options for decompression
+- FileReadPost		decompress the file
+
+Note: This test will fail if "gzip" is not available.
+$GZIP is made empty, "-v" would cause trouble.
+Use a FileChangedShell autocommand to avoid a prompt for "Xtestfile.gz" being
+modified outside of Vim (noticed on Solaris).
