Given a file of source lines that look like the following, I would like to splice together 
lines with escaped new lines but preserve the line numbers.

'''Input File'''
----
 line(1)
 line(2)\
 line(3) with space after excape\    
 line(4)\
 line(5)
 line(6)\
 line(7)
 line(8)
----

'''Solution'''

 set fid [open [file normalize "./filename"] r]
 set text [read ${fid}]
 close $fid
 regsub -all -- {[\\][ \t]*[\n]} ${text} "\\\n" text
 while { [regsub -all -- {[\\][\n](.*?[^\\])[\n]} ${text} "\\1\n\n" text] } {}

'''Result'''
 >% puts $text
 >line(1)
 >line(2)line(3) with space after excapeline(4)line(5)
 >
 >
 >
 >line(6)line(7)
 >
 >line(8)
 >
 >%

Notice that the lines have been spliced together and the spliced lines 
occur on the corrent line in the output.
