bd388d2b6c jshn: do not collapse whitespace in json_load() 
When running the test case below the $key variable holds "foo bar" instead
of the expected "foo  bar".

-- 8< --
. /usr/share/libubox/jshn.sh
json_init
json_load '{ "key": "foo  bar" }'
json_get_var key key
-- >8 --

Quote the output of the "jshn -r" backtick expression to prevent the shell
from erroneously collapsing whitespace.

592f2dbd82 sh/jshn.sh: allow numbers in identifiers for json_get_var() 
When traversing arrays of tables or arrays of array it is required to
call json_select # where # is the index of the array item to select.

Internally json_select() calls json_get_var() to obtain the correct
prefix to populate $JSON_CUR with. However, the "tr" call in
json_get_var() incorrectly replaces all digits with underscores,
making any lookup for numeric array items fail.

The attached patch changes the "tr" expression to allow digits and
thus implements the expected behaviour for nested arrays.
