The backslashes aren't there for the shell, they are there for the git
config parser. Anyway, I reworked it a bit:

alias = "! sh -c 'case $# in \
               0) git config --get-regexp \"^alias\\.\" \
                  | sort | sed \"s/^alias\\.//; s/=/ /\" \
                  | while read n v; do \
                     printf \"%-16s\" \"$n\"; \
                     echo \"$v\" | fmt -sw 63 | sed \"2,$ s/^/\t\t/\" ;\
                  done ;; \
               1) git config \"alias.$1\" | fmt -sw 78 ;; esac' -"

And yes, it's still ugly.

Always happy to have folks help me bikeshed my git config. :-)
