Comment(by donxfive):

 {{{
 is the change to the first sed expression just a simplification, or does
 it contribute to the bug?
 }}}

 The answer is "yes and no:" when I used the plus sign in the second
 expression, I needed to invoke sed with the "-r" option to get it to work,
 and that caused sed to choke on the first expression so I changed it.

 By the way, I just tried
 {{{
 sed  -e 's/^\([PLBCFKA]\)/#\1/' -e 's/^ [1-9]\+  /#&/'
 }}}
 (ie using sed without the "-r" option, and using "\+" rather than "+" in
 the second expression), and now the first expression works fine. I think
 that both the "-r" option and "\+" are specific to GNU sed, so I'm not
 sure about the portability of my workaround. Maybe something like this
 would be better:
 {{{
 sed  -e 's/^\([PLBCFKA]\)/#\1/' -e 's/^ [1-9][1-9]*  /#&/'
 }}}
 This works the same as my first workaround, but is probably more portable.
