wget: increase redirections limit

2019-10-21T14:54:40+00:00

Some hosting services like sourceforge perform a lot of relocations
before actually serving the file. Example of current limitation:

    busybox wget http://sourceforge.net/projects/fluxbox/files/fluxbox/1.3.7/fluxbox-1.3.7.tar.xz
    Connecting to sourceforge.net (216.105.38.13:80)
    Connecting to sourceforge.net (216.105.38.13:443)
    Connecting to sourceforge.net (216.105.38.13:443)
    Connecting to sourceforge.net (216.105.38.13:443)
    Connecting to downloads.sourceforge.net (216.105.38.13:443)
    wget: too many redirections

dc: execute shouldn't pop if stack head is not a string

2019-10-21T14:54:40+00:00

This matches the behaviour of both GNU dc (as specified in
its man page), and BSD dc (where stack_popstring() pops
only if the head is a string.)

Add a couple of tests to verify this behavior.
