GoShare should support sharing a specific file, not the entire directory where the file is located

[duruyao]

I just want to share the file HELLO.txt, but the whole directory is shared.

$ echo $PWD
/home/duruyao/tmp
$ ls
HELLO.txt  HI.txt

$ goshare -v
GoShare 1.1.0 (2022-05-26)
$ goshare --path HELLO.txt

   _____       _____ _
  / ____|     / ____| |
 | |  __  ___| (___ | |__   __ _ _ __ ___
 | | |_ |/ _ \\___ \| '_ \ / _' | '__/ _ \
 | |__| | (_) |___) | | | | (_| | | |  __/
  \_____|\___/_____/|_| |_|\__,_|_|  \___|


GoShare is handing directory '/home/duruyao/tmp' and listening on 'localhost:3927'

Access your shared files via this URL http://localhost:3927/HELLO.txt

$ curl -kSsL http://localhost:3927/HI.txt -o HI.txt.bak
$ curl -kSsL http://localhost:3927/HELLO.txt -o HELLO.txt.bak
$ ls
HELLO.txt  HELLO.txt.bak  HI.txt  HI.txt.bak
