The manual says:
       ${parameter##word}
              The  word  is expanded to produce a pattern just as
              in pathname expansion.  If the pattern matches  the
              beginning  of  the  value  of  parameter,  then the
              result of the expansion is the  expanded  value  of
              parameter  with  the shortest matching pattern (the
              ``#'' case) or the longest  matching  pattern  (the
              ``##''  case) deleted.

I tried to experiment with it, but I could not get anything usefull from it.

See the comment in the script:
# remove session management file from welcome page, if user do not save 
session
# this is only needed before SuSE 7.2
rm -f "${kdehome}"/share/config/${konq_sm_file##*/}
