And, the .* would allow for one or more comma-separated fields, both in the middle as well as at line end. You might want to anchor the regex at line end, too. Proposal (untested)


Code:
sed -r 's/^([^,]*,){2}bcd,.*,([^,]){4}[^,]*$/&,\2/'

gmtlogo

GMTLOGO(1gmt)						       Generic Mapping Tools						     GMTLOGO(1gmt)

NAME

       gmtlogo - Adding a GMT graphics logo overlay to an illustration

SYNOPSIS

       gmtlogo dx dy [ -Gfill ] [ -W[pen] ] >> plot.ps

DESCRIPTION

       This  scrips  appends the GMT logo to an "open" PostScript file.  The logo is 2 inches wide and 1 inch high and will be positioned with the
       lower left corner at the position (dx,dy) relative to the current plot origin.

OPTIONS

       -G     Select color or pattern for filling the underlying box [Default is no fill].  (See SPECIFYING FILL below).

       -W     Set pen attributes for the outline of the box [Default is no outline].  (See SPECIFYING PENS below).

   SPECIFYING PENS
       pen    The attributes of lines and symbol outlines as defined by pen is a comma delimetered list of width, color and texture, each of which
	      is  optional.   width  can  be  indicated  as  a	measure  (points, centimeters, inches) or as faint, thin[ner|nest], thick[er|est],
	      fat[ter|test], or obese.	color specifies a gray shade or color (see SPECIFYING COLOR below).  texture is a  combination	of  dashes
	      `-' and dots `.'.

   SPECIFYING FILL
       fill   The  attribute  fill specifies the solid shade or solid color (see SPECIFYING COLOR below) or the pattern used for filling polygons.
	      Patterns are specified as pdpi/pattern, where pattern gives the number of the built-in pattern (1-90) or the name of a Sun  1-,  8-,
	      or  24-bit  raster  file. The dpi sets the resolution of the image. For 1-bit rasters: use Pdpi/pattern for inverse video, or append
	      :Fcolor[B[color]] to specify fore- and background colors (use color = - for transparency).  See GMT Cookbook &  Technical  Reference
	      Appendix E for information on individual patterns.

   SPECIFYING COLOR
       color  The  color  of  lines, areas and patterns can be specified by a valid color name; by a gray shade (in the range 0-255); by a decimal
	      color code (r/g/b, each in range 0-255; h-s-v, ranges 0-360, 0-1, 0-1; or c/m/y/k, each in range 0-1); or  by  a	hexadecimal  color
	      code (#rrggbb, as used in HTML).	See the gmtcolors manpage for more information and a full list of color names.
