Index: uncompress.el
If you visit a compressed file that you can't write, the compressed file
is placed in a read-only buffer. Subsequent execution of
shell-command-on-region to uncompress the contents of the buffer fails
because the buffer has been marked read-only.
Suggested fix:
(defun uncompress-while-visiting ()
"Temporary \"major mode\" used for .Z files, to uncompress the contents.
It then selects a major mode from the uncompressed file name and contents."
(if buffer-read-only ;; Allow uncompress on the buffer - bjb
(toggle-read-only)) ;;
(if (and (not (null buffer-file-name))
(string-match "\\.Z$" buffer-file-name))
(set-visited-file-name
(substring buffer-file-name 0 (match-beginning 0))))
(message "Uncompressing...")
(shell-command-on-region (point-min) (point-max) "uncompress" t)
(message "Uncompressing...done")
(set-buffer-modified-p nil)
(normal-mode))
