Small bug with [output directory] parameter

[fititnt]

If the [output directory] does not have last "/", it will prepend last diretory name to the file names. Example:

node /alligo/code/adrianba/multipage/multipage.js /alligo/code/w3c/html/single-page.html /alligo/code/w3c/html/out --max-old-space-size=3072

Output

# fititnt at bravo in /alligo/code/w3c/html on git:master x [5:33:41]

It works only if last use last "/" at the end of path, i.e. node /alligo/code/adrianba/multipage/multipage.js /alligo/code/w3c/html/single-page.html /alligo/code/w3c/html/out/ --max-old-space-size=3072 will create the files at /alligo/code/w3c/html/out
