GIT e067e1f98d54d62fd598126f95e7684e5b63e67f master.kernel.org:/pub/scm/linux/kernel/git/sam/kbuild.git commit e067e1f98d54d62fd598126f95e7684e5b63e67f Author: Sam Ravnborg Date: Mon Nov 21 22:59:32 2005 +0100 kconfig: truncate too long menu lines in menuconfig menu lines wrapped over too lines when too long - truncate them. Also fixed a coding style issue Signed-off-by: Sam Ravnborg commit 59d3cf7a40dfdbb8e86758ade172831c19630050 Author: Sam Ravnborg Date: Sun Nov 20 23:34:35 2005 +0100 kconfig: make lxdialog/menubox.c more readable Utilising a small macro for print_item made wonders for readability for this file. Signed-off-by: Sam Ravnborg commit 7c3badf96e0dc8aa89ebf8919653339a5ee8e035 Author: Sam Ravnborg Date: Sun Nov 20 23:03:49 2005 +0100 kconfig: Fix indention when using menuconfig in text-onle consoles When using menuconfig in a text-only console (no X started) the indention was often two spaces wrong. This proved to be a ncurses issue which are worked around by calling wrefresh more often. Signed-off-by: Sam Ravnborg commit 0e175d05a4e72f85918da3ea4bd9f5d3d78face4 Author: Sam Ravnborg Date: Sun Nov 20 22:41:21 2005 +0100 kconfig: Left aling menu items in menuconfig Keeping menu lines on a fixed position creates less visual noise when navigating the menus.

Signed-off-by: Sam Ravnborg commit dec69da856653772d7ee7b2f98dc69da27274a22 Author: Sam Ravnborg Date: Sat Nov 19 21:56:20 2005 +0100 kconfig: fixup after Lindent Readability are more important then the 80 coloumn limit, so fold several lines to greatly improve readability. Also keep return type on same line as function definition. Signed-off-by: Sam Ravnborg commit b1c5f1c635f4a821f834ed51ccd8a2a1515fffd2 Author: Sam Ravnborg Date: Sat Nov 19 19:13:34 2005 +0100 kconfig: Lindent scripts/lxdialog The lxdialog code was not easy to read. So as first step the code was run through Lindent. Fix-ups will come in next patchset.
