Git fetch fails and never completes

[maxmilton]

There's 2 issues that prevent this theme from working out-of-the-box.

First, the stat call does not work with my version of stat. Possibly a OS difference or I'm using a newer version (stat (GNU coreutils) 8.29). There's an existing PR to fix this #10 .

Second, the actual git fetch fails. If I run env GIT_TERMINAL_PROMPT=0 command git -c gc.auto=0 fetch in a terminal the output is:

env: ‘command’: No such file or directory

Removing command so it's just env GIT_TERMINAL_PROMPT=0 git -c gc.auto=0 fetch allows things to work as expected but may not be the best option. I'm not very familiar with fish scripting so perhaps there's a better solution.
