Denys Vlasenko 4ebcdf7396 hush: remove code to track PS1/2 values dynamically - it's too much work 
Assignments / exports / unsets of variables are far more frequent than
prompt printing, and if we show prompt, we are likely to be limited by
user typing speed - do not optimize for that scenario.
Just re-query $PS1 / $PS2 values when need to show the prompt.

Denys Vlasenko bae8f7eaf2 httpd: do not percent-decode URI if proxying 
The proxying is documented as follows:

P:/url:[http://]hostname[:port]/new/path

Howeverm urlcopy is not a true copy anymore when it is fdprint'ed
to proxy_fd, this is because percent_decode_in_place() is called
after the copy is created.

This breaks reverse proxying all URIs containing percent
encoded spaces, e.g. - because a decoded URI will be printed out
to proxy_fd instead of the original.

The fix keeps the logic in place to canonicalize the uri first,
before reverse proxying (one could argue that the uri
should be proxied completely unaltered, except for the prefix
rewrite).

Denys Vlasenko 1e474d3d93 service examples: if iface do not exist, retry upping it 
I've had a case of a machine where eth0 was appearing a bit later
after the boot, and appearing _downed_. ifplugd then fails to detect
"link up". Thus, depending on how service startup
("ip link set dev eth0 up") races with driver initialization,
ethernet randomly fails to initialize on boot.
