Max amount of exclude statements

[Alexander Zierhut]

While working on #623, I tried a temporary fix by using the exclude statement like so:

minify
--recursive
--verbose
--exclude '**/folder1/**'
--exclude '**/folder2/**'
--exclude '**/folder3/**'
--output folder_output/
folder_input/

This results in:
minify: must specify --type in order to use stdin and stdout

Possibly relevant code

Thanks, this was silly...there was still some debugging code in the argp package which prevented from parsing too many arguments. Should be fixed now.

On the issue, --exclude allows to pass multiple values, such as: --exclude '**/folder1/**' '**/folder2/**' '**/folder3/**' would work fine. This might give unexpected results when it is followed immediately by the input files, as it would be included in the excludes, and not inputs: --exclude dir_to_exclude folder_input would be unexpected. You would need to do: --exclude dir_to_exclude -- folder_input. I'm not 100% convinced if this is the way of "least surprises" by users...
