Hello Michal, this is just a cosmetical issue and probably I oversee a reason why print_autowrap() ignores newline characters: When I exit menuconfig with unsaved changes I get a dialog that looks like Do you wish to save your new configuration ? <ESC><ESC> to continue. and I thought that could look prettier (and probably should use complete sentences). In mconf.c, the above text is defined with a newline, so I guess the author expected it to be processed, but the comment before print_autowrap() clearly states that newline characters will be replaced by spaces. I am not sure if this is a must -- I did not find a reason why print_autowrap() should not process newline characters and gave it a try. Attached is a first version of a patch. There are other (indirect) users of print_autowrap() but for now I just modified the text for the exit dialog.

When exiting menuconfig with unsaved changes, a dialog like the following is shown Do you wish to save your new configuration ? <ESC><ESC> to continue. The author of the dialog text specified a newline and probably expected it to be processed, so let print_autowrap() handle newlines propperly. --- scripts/kconfig/lxdialog/util.c | 34 ++++++++++++++++++++++------------ scripts/kconfig/mconf.c | 8 ++++---- 2 files changed, 26 insertions(+), 16 deletions(-)
