Trailing space in file name

[Iwanna Beer]

I'm running Ubuntu (Linux osboxes 5.8.0-50-generic #56~20.04.1-Ubuntu SMP Mon Apr 12 21:46:35 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux) in VirtualBox VM.

Filenames ending with windows CR (CRLF) contains trailing space in name.

Steps to reproduce:
copied filename on windows host (Wordpad) and pasted to Ubuntu shell (same with `touch`)
```
osboxes@osboxes:~/dev/eXtraGames/02$ vim 07_extract_snippets.sh
osboxes@osboxes:~/dev/eXtraGames/02$ ls
07_extract_snippets.sh  stdin test
osboxes@osboxes:~/dev/eXtraGames/02$ mv 07_extract_snippets.sh 07.sh
mv: cannot stat '07_extract_snippets.sh': No such file or directory
osboxes@osboxes:~/dev/eXtraGames/02$ mv 07_extract_snippets.sh  07.sh
osboxes@osboxes:~/dev/eXtraGames/02$ ls
07.sh stdin test
osboxes@osboxes:~/dev/eXtraGames/02$ mv 07.sh 07_extract_snippets.sh
osboxes@osboxes:~/dev/eXtraGames/02$ ls
07_extract_snippets.sh stdin test
```
