2016-03-06ls: fix columnar output. Closes 8731Denys Vlasenko
In coreutils/ls.c, 1.19 introduced commit 2f7d9e8903029b1b5e51a15f9cb0dcb6ca17c3ac, removing the variable tabstops and hard coding the column separation to 2 characters, but was not done correctly. The column_width assumes a gap of 1 character, so the computed number of columns exceeds the terminal width when many small files are encountered. A minor problem but surprisingly annoying.

2015-07-31echo: make escape sequences depend on fancy modeMike Frysinger
Currently when you disable fancy echo, escape sequences are hardcoded enabled (e.g. as if you used `echo -e` all the time). The opposite behavior is more desirable (always disable -e support) because: * This seems to contradict the spirit of the kconfig help text (where it says enable support for -n/-e flags), although you could say that we aren't supporting the -e flag directly as `echo -e` will show the -e flag. * POSIX makes escape sequences optional, and even says they are there only on XSI-conformant systems. * It saves space (~100 bytes on x86_64). * It makes things faster! * It makes it behave more like bash where you need an explicit -e flag in order for escape sequences to be interpreted.
