CVSROOT: /sources/emacs
Module name: emacs
Changes by: Juri Linkov <jurta> 09/08/22 00:17:48
Modified files:
lisp/progmodes : grep.el
Log message:
(lgrep, rgrep): At the beginning
set `dir' to `default-directory' unless `dir' is a non-nil
readable directory. (Bug#4052)
(lgrep, rgrep): Change a weird way to report an error
from using `read-string' to using `error'.
Instead of using interactive arguments in the function body,
add new argument `confirm'.
