Patch for mfold 1.05, to get mfold 1.06

[Peter Smidt]

This is a patch for mfold 1.05 to get 1.06. 
When the insert text (using the '-i' flag) is one character long the '-n' flag
won't work properly. It removes the empty lines, instead of keeping them.
This patch will make the above two flags work as they are expected to do,
together. ))

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of shell archive."
