The actual help text looks like this:

```
> ./bin/lldb-server p -h
OVERVIEW: lldb-server platform

USAGE: lldb-server p [options] --listen <[host]:port> [[--] program args...]
```

The regex is only needed with the double brackets, so there were a couple that were unnecesary. Should be fixed now. 

It's only needed at the `[[--]` part because `[[` is interpreted by FileCheck as variable substitution. For example in `cross-project-tests/dtlto/link-archive-thin.test` PID is substituted:
```
## JSON jobs description.
OUTPUTS-DAG: my.[[PID:[a-zA-Z0-9_]+]].dist-file.json

## Individual summary index files.
OUTPUTS-DAG: start.1.[[PID]].native.o.thinlto.bc{{$}}
OUTPUTS-DAG:   dog.2.[[PID]].native.o.thinlto.bc{{$}}
OUTPUTS-DAG:   foo.3.[[PID]].native.o.thinlto.bc{{$}}
OUTPUTS-DAG:   bar.4.[[PID]].native.o.thinlto.bc{{$}}
```
