Fix segfault for sh -c 'echo {a..Z}'
Bash produces different output for that test, but I'm not sure I care?
http://lists.landley.net/pipermail/toybox-landley.net/2020-September/011990.html
The problem is parse_word() guarantees its output's quotes/escapes
are completed, but brace expansion happens after parse_word() and thus
violating assumptions later code depends on to not do redundant error
checking. The easy fix is to escape punctuation produced by parse_word
(which in bash can only happen when you span upper and lower case ranges
so "\" is the only interesting character). I could special case this to
match bash exactly, but I'm waiting for someone to complain instead.
