uci batch stderr problem

[systemcrash]

Minor bug, but when running batch commands, some iterator seems to affect stderr:

uci: Entry not found
uci: Entry not found

uci: Entry not found


uci: Entry not found



uci: Entry not found




uci: Entry not found





uci: Entry not found






uci: Entry not found

Note that the amount of empty lines corresponds to which iteration uci is currently on.

for commands such as:

uci batch << EOI
get something.@something[0].somekey
get something.@something[1].somekey
get something.@something[2].somekey
get something.@something[3].somekey
get something.@something[4].somekey
get something.@something[5].somekey
get something.@something[6].somekey
get something.@something[7].somekey
get something.@something[8].somekey
get something.@something[9].somekey
EOI

I also ran into this. It seems to have been introduced in ead1a3c.

Since error_info is static, each call concats a \n to error_info.

Something like this would truncate the string and fix the issue.

static char error_info[128] = { 0 };
error_info[0] = 0;
