Hi,

 handbook/printing/chapter.sgml suggests a filter script `ifhp' to
 examine if the printing data is in PostScript or not, but when
 the data is a plain text, spaces in the first line are chopped
 by the script.  `read' chops spaces at the head of the line,
 and `echo' converts continuous spaces into a single one.
 I think this is an undesirable behavior.

 Could anyone review the attached patch contributed by
 Kimura-san(one of doc-jp translators) to fix the problem?
 I will commit this if no one complains in a couple of days.
