cli: Avoid storing empty lines in command history
When the console manager is run in the interactive mode, it also saves empty lines (i.e. the Enter key is pressed without running a command) in it's command history. Avoid this by processing the line only if readline() returns a non-empty string. Makes it easier to navigate the history using arrow keys. modified: cli/src/cli-rl.c Change-Id: I0fcce394474589bb345b7c9ef39d25849dc0c2af BUG: 957139 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/4894 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
