test-powerline: Allow for 2 cell wide glyphs

Browse source 
[why]
When testing 'Nerd Font' fonts (i.e. symbols may be 2 cells wide),
the output does not take that into account and does not insert
the needed blanks.

[how]
Because the actual width can not be easily determined add a
parameter (just add anything as parameter) to switch some glyphs
to two cell mode. These glyphs are in a list, i.e. hardcoded.

If the widths in non-Mono fonts is ever changed this script needs
to be adapted.
