[RCD] Why does RC remove leading blanks when displaying quoted lines?

Due to some reason RC does remove leading blanks when displaying quoted lines such as:

Reply-To: theo@test.de, Roundcube Users mailing list users@lists.roundcube.net

Reply-To: theo@test.de, Roundcube Users mailing list users@lists.roundcube.net

The blanks are there, they're just not displayed. That's a bit annoying especially when plain text tables are quoted:

Version RC 0.8.2 RC 09-git

         yes        no
         no         yes

Version RC 0.8.2 RC 09-git

         yes        no
         no         yes

See? Can this be avoided?
