alias and begining space in prefix / suffix

[chtiland]

Creating an alias with a suffix (or prefix) beginning with a space doesn't work, begining spaces are deleted.

e.g. : Plugin Amazon Type : "wiki" Prefix : "{{amazon>fr:" suffix : " noprice 1}}"

More simple exemple : One field for an integer. I want to add a space followed by €.

I also tried to use   but doesn't work too.
