Apparently you cannot add spaces to stash names anymore

Reproduce steps:

• Change some code
• Click the Stash button
• Type in some words eg "This is my stash comment"
• Error occurs:
  • The stash desc is invalid. Ref names must follow git ref-format rules:

    Completed with errors, see above.
•  Close error dialog

• Click the Stash button again

• Type in some words without spaces eg "This_is_my_stash_comment"
• Stash is successful.
