[PATCH v3 0/6] Better ref summary alignment in "git fetch"

This is so people can play with new output format... v3 adds one extra
pass to calculate width (4/6) and swap flag code 'x' and '-' with '-'
and 't' to align with push flag code (3/6). These are definitely good
improvements.

5/6 and 6/6 add two new formats "{ -> origin}/abc" and "abc -> origin/$".
Format output is selected by config key fetch.output. I'm tempted to
replace '$' with '&' as it usually means "what was matched" in s///

I don't think we'll want both new formats in the end. One of them (or
a new format) will win as the optional format. The aligned "remote ->
local" should stay default format. And later on we could break lines
at "->" for very long lines as Marc suggested.
