fetch: align all "remote -> local" output

Browse source 
We do align "remote -> local" output by allocating 10 columns to
"remote". That produces aligned output only for short refs. An extra
pass is performed to find the longest remote ref name (that does not
produce a line longer than terminal width) to produce better aligned
output.
