[Geiser-users] [BUG] Hanging while completing symbol in a Racket filename which contains a white space

[Diogo F. S. Ramos]

1. C-x C-f /tmp/foo bar.rkt RET
2. Insert `#lang racket '
3. Save it and enter file with C-c C-a
4. Type `(li[TAB]'

Now the process hangs.

AFAICS it loops indefinitely at a `while' in
`geiser-con--send-string/wait' but I can't understand why.
