Comment:

 Specifying a title leads to a parse error:

 {{{
 GRASS 7.2.svn (latlong_wgs84):~/Downloads > d.legend raster="magnitude"
 at=90.3,94.7,1.8,26.5 title="Wind magnitude [knots]"
 Drawing horizontal legend as box width exceeds height

 }}}

 Likewise with NC SPM:
 {{{
 GRASS 7.2.svn (nc_spm_08_grass7):~ > d.legend raster=elevation
 title="Elevation [m]"
 GRASS 7.2.svn (nc_spm_08_grass7):~ > ERROR: Failed to run command
 'd.legend raster=[m] at=5,50,47,50
        title=Elevation'. Details:

        GRASS_INFO_ERROR(16739,1): Raster map <[m]> not found
        GRASS_INFO_END(16739,1)
 }}}

 "Just" a quoting issue it seems.
