Cleaning double spaces never terminates

Time: 0:00

What it should do

squash_spaces(text) should collapse runs of spaces into one, so squash_spaces("a b") returns "a b".

What goes wrong

squash_spaces("a b") returns immediately, but squash_spaces("a b") hangs forever.

Hints

This is an infinite loops bug

The tab freezes, nothing prints, and the loop condition never becomes false.
