getip function has trailing newline

[benknoble]

Current behavior

${PS1} $ getip 
xx.x.x.xx
                     # spaces added to show where newline is

Desired behavior

${PS1} $ getip 
xx.x.x.xx

Fix

Remove echo from function definition:

getip () 
{ 
    ipconfig getifaddr en0;
    # remove this # echo
}
