Issue with short arg parsing using optional space

[kdawgwilk]

The docent standard supports an optional space after short args like -c 50 and should be parsed into a "-c": "50" but it currently is parsed into "-c": " 50" which has the side effect of not being able to be coerced into a int type because of the space

From docent.org

Short options can have arguments specified after optional space:
-f FILE is equivalent to -fFILE.
