[Pkg-zsh-devel] Bug#654444: zsh: `q' flag for paramater expansion does not work as advertised

[Samuel Bronson]

Package: zsh
Version: 4.3.12-1
Severity: normal

The manual says this about the flag:

,----
| q
|      Quote the resulting words with backslashes; unprintable or invalid
|      characters are quoted using the $'\NNN' form, with separate quotes
|      for each octet.  [...]
`----

Unfortunately, the second clause seems to be only half correct;
unprintable characters do get wrapped in $'...', but not \NNN escaped:

,----
| naesten at hydrogen:~/hacking/crawl/crawl-ref/source% echo -n ${(q)$(echo
| -e "\e")}|hd
| 00000000  24 27 1b 27                                       |$'.'|
| 00000004
`----

Of course, what I'd *really* like would be for this to get escaped as
\e, not \NNN, but I was at least expecting the documented behavior!
