Multiple space in code will also become subject of squish

[akicho8]

Thank you for a wonderful library.

There is one thing in trouble. It is a little inconvenient to squish multiple spaces. It is good to make one space before and after a line break. But, if possible, I do not want squish the space in the code. Please consider.

Steps to reproduce

every 1.hour do
  runner "p '  '"
end

Expected behavior

0 * * * * /bin/bash -l -c 'cd /path/to/myapp && bin/rails runner -e production '\''p '\''\'\'''\''  '\''\'\'''\'''\'' >> log/cron.log'

Actual behavior

0 * * * * /bin/bash -l -c 'cd /path/to/myapp && bin/rails runner -e production '\''p '\''\'\'''\'' '\''\'\'''\'''\'' >> log/cron.log'

Multiple spaces are now one.
