To allow paths with spaces, give a shell-quoted path to hyperfine. We
could make this a bit shorter by quoting as early as possible, like
FISH_PATH=$(quote "$1")
and then use $FISH_PATH unquoted. I discarded that idea because it
probably looks surprising.

Summary
'build/fish benchmarks/benchmarks/math.fish > /dev/null' ran
1.14 ± 0.05 times faster than 'fish benchmarks/benchmarks/math.fish > /dev/null'
This did some weird unescaping to try to extract the first word.
So we're now more likely to be *correct*, and the alias benchmark is
about 20% *faster*.
Call it a win-win.
