[10.x] Process::fake() never matches a multi-line command (or, Str::is() always returns false on multi-line strings)

Description

My code does this:

$result = Process::run(<<<BASH
git clone --depth 1 \
      --single-branch \
      --branch master \
      git://some-url .
BASH);

My test tries to do this:

Process::preventStrayProcesses();

Process::fake(['*' => 'faked output']);

This doesn't work and always throws an "Attempted process without a matching fake" exception because:

• The Process fake tries to match the command using Str::is()
• The regex used by Str::is() doesn't have the m option (treat as multi-line string) (edit: m doesn't work, it needs the s option)
• Without the m option, the regex used by Str::is() always returns false on multi-line strings

I've tried a bunch of patterns, but it seems to be impossible to get Process::fake() to match a multi-line command.

Steps To Reproduce

Process::preventStrayProcesses();

Process::fake(['*' => 'faked output']);

$result = Process::run(<<<BASH
git clone --depth 1 \
      --single-branch \
      --branch master \
      git://some-url .
BASH);

Hi @SjorsO. Appreciate the report but this seems like something that's just not possible at the time. If you could send in a PR to make this possible we'd appreciate a PR. Make sure to add tests. Thanks!
