Possible CommandSection strip_whitespace regression, now removes the first word on the first line

[thatRichman]

I noticed this after I rebased #264 following the merge of #265 .

Take for example the following Command section:

command <<<      weird stuff $firstlinelint
            # other weird whitespace
      somecommand.py $line120 ~{placeholder}
>>>

The first StrippedCommandPart returned from strip_whitespace

Prior to c5c1553:

Text(
    "weird stuff $firstlinelint\n      # other weird whitespace\nsomecommand.py $line120 ",
)

after c5c1553:

Text(
    "stuff $firstlinelint\n      # other weird whitespace\nsomecommand.py $line120 ",
)

Was this intentional or is it a bug?

Definitely a bug. Looking into it this morning. Thanks for catching this edge case!
