unset property and property with empty string

[luvarqpp]

Expected behavior

when using (for example) bandwidth block with config like this:

[bandwidth]
INTERFACE=eth0
interval=5
INLABEL=
OUTLABEL=⇵

I would expect resulting bar to be something like this: XXX 32K⇵8K XXX

Actual behavior

Actually, there are two problems:

• One is adding single space just before OUTLABEL. I can add single space to OUTLABEL, if I want it. But now I am not able to remove it without editing sourcecode of bandwidth.
• INLABEL set to emply string is evaluated as it would not be set at all and is defaulted to "IN ".

i3blocks config relevant to blocklet(s)

[bandwidth]
INTERFACE=eth0
interval=5
INLABEL=
OUTLABEL=⇵

Output of blocklet(s) when run from command line

some other block IN 0K ⇵0K another block

Expected behavior is:

some other block 0K⇵0K another block
